PHP - Seriuos Problem With Collecting Result In Recursive Function
Hi there, hope one of you can help me with a problem im just having.
Ok, lets start with the explanation what i want to to: I'd like to collect headlines from a html site, and get the test results in an array, so that the array structure represents the dom-levels of the site. Small Example: <h1>test1.1<h1/> <h2>test2.1</h2> <h2>test2.2</h2> <h3>test3</h3> <h1>test1.2<h1/> Shoul end in a array structure like: Code: [Select] array('level 1' => array ( 'sibble1' => array ( 'headline' => 'test1.1', 'level2' => array( 'sibble1' => array ( 'headline' => 'test2.1', 'level3' => array(), // empty data, needs to be processed anyway to find gaps, to maybe a h4 headline would be existing ), 'sibble2' => array ( 'headline' => 'test2.2', 'level3' => array ( 'sibble1' => array ( 'headline' => 'test3.1', 'level4' => array(), // empty data, needs to be processed anyway to find gaps, to maybe a h4 headline would be existing ), ), ), ), ), 'sibble2' => array ( 'headline' => 'test1.1', 'level2' => array(), ), ), ); So i hope out of this example you can see what i want to do. level represents the healdine level 1-9, sibblin is as name for the childs on the headline level. Ok, so to extract the herefore needed data out of the html, i build a class with a recursive function, that filters the html by a regex from one headline to the next, first iteratin all childs, if there are no more childs i go tho ne nextsibbling element. as an running example code look he Code: [Select] <?php class Application_Model_DomParser { const PREG_MATCH_ONE_ELEMENT_TO_MUCH_LENGTH = 4; private $slicedFields = array(); public function __construct() { } public function sliceFirstSectionToDataFields($level = 1, $haystack) { preg_match_all("#(.*?)<h$level>(.*?)</h$level>(.*?)(<h$level>|$)#s", $haystack, $data); // prepare the chunkData $pageText = ''; if (isset($data[1][0])) { $pageText = $data[1][0]; } $headline = ''; if (isset($data[2][0])) { $headline = $data[2][0]; } $dataToProcessNextLevel =''; if (isset($data[3][0])) { $dataToProcessNextLevel = $data[3][0]; } // @todo dirty warnings compression, search why warning occures @$posOfNextChild = strlen($data[0][0]) - self::PREG_MATCH_ONE_ELEMENT_TO_MUCH_LENGTH; // from here goes the debug... echo $headline ."::" .strlen($dataToProcessNextLevel). "<br>"; if (strlen($dataToProcessNextLevel) <= self::PREG_MATCH_ONE_ELEMENT_TO_MUCH_LENGTH) { if ($level < 9) { $dataToProcessNextLevel = $haystack; } else { return; } } //recursive check for next level in $dataToProcessNextLevel $nextLevel = $level + 1; $this->sliceFirstSectionToDataFields($nextLevel, $dataToProcessNextLevel); $haystack = substr($haystack, $posOfNextChild); // slized To The End if (self::PREG_MATCH_ONE_ELEMENT_TO_MUCH_LENGTH == strlen($haystack)) { // die("slized To The End"); return; } // recursive check for other childs in actuall level... $this->sliceFirstSectionToDataFields($level, $haystack); } } $htmlString = 'test<h1>headkline1.1</h1> <p>test test</p> <h2>headline 2.1</h2>test test <h2>headline 2.2</h2> <p>tes test test</p> <h3>headline 3.1</h3>test <h3>headline 3.2</h3>test <h2>headline 2.3</h2> <p> </p> <p>test</p> <h1>headline 1.2</h1> <h2>headline 2.4</h2> <p>11111111111112222222222222222222222</p> <p> ewfwrefg upowmdg w3q09umq09wrt n3q089ty 3q0898943ty -98 41</p> <h3>headline 3.3</h3> <p>test</p> <p>test</p> <p>test</p> <h1>1.3 testtest</h1> <p>test</p> <h3>head 3.4</h3> <p>sadfsadfsadf asdfsda f sdaas saf saddas</p> <h3>head 3.4</h3> <h3>test 1.3</h3> <p>test;</p> '; $model = new Application_Model_DomParser(); $result = $model->sliceFirstSectionToDataFields(1, $this->htmlString); So letting this piece of code run, you can se via the debug echo, every headline is found, even in the right order of its occurence. My problem now is dont get it how to return the extracted values, and collect them to get a result as my above shown structure shows. So i spent ours to solve this problem but didnt come to a result. I know its a hard problem, and to help me takes time, cause its a complex situation. Allthough i hope someone knows a anser. I need this problem solved, to get my mind rested! Thanks, and greetings Selma Similar TutorialsHello! Maybe I'm a bit ashamed to question some little kind of thing, but I tested 3 hours and couldn't let this function. It's like the most easiest possible recursiv function...: Code: [Select] function recursiv($s){ $s.="b"; if(strlen($s)>30){return $s;} //else return 0; else recursiv($s); } echo recursiv("h"); The result is a blank page... Thanks a lot for your help !! Hi there, I have written a recursive function that basically generates a tree structure for my site pages (kind of like a sitemap). It all worked fine until yesterday, I started getting error messages telling me that I have exhausted the amount of memory available. There are only about 30 pages in the site (parent, child, sub-child etc), so I dont think that I should be using up that much memory. This was my first attempt at a recursive function so I am pretty sure that it may not have been optimised properly. If anyone could take a look and offer any feed back that would be great. (written in codeigniter framework) function getAllPages() { $this->tmp_arr = array(); $this->buildPageStructure(0, 0); return $this->tmp_arr; } function buildPageStructure($parent_id, $counter) { $CI = & get_instance(); $query = $CI->db->query("SELECT page_id, title, page_url, status FROM pages WHERE parent_page='$parent_id' ORDER BY sort_order ASC"); $counter++; if($query->num_rows() > 0) { foreach($query->result() as $row) { $new_arr = new Page(); $new_arr->page_id = $row->page_id; $new_arr->title = $row->title; $new_arr->level = $counter; $new_arr->page_url = $row->page_url; $new_arr->status = $row->status; $this->tmp_arr[] = $new_arr; $this->buildPageStructure($row->page_id, $counter); } } } Cheers Jon Hey guys, I've got a problem. I need a function, that gives me a menue like that: parent_page1 page1 page2 page3 parent_page2 page1 page2 page3 So.. here is my database structu All what I need, is a function, that gives me a menu like that on top. Do you need some more information? Let me know.. i have the below script but it doesn't work it just refreshes the page anyone know what is wrong Code: [Select] <?php $path = "../../gallery/gallery_files/gallery/"; if(isset($_POST['file']) && is_array($_POST['file'])) { foreach($_POST['file'] as $file) { $dirname = $path; //Recursive Delete Function function DELETE_RECURSIVE_DIRS($dirname) { // recursive function to delete // all subdirectories and contents: if(is_dir($dirname))$dir_handle=opendir($dirname); while($file=readdir($dir_handle)) { if($file!="." && $file!="..") { if(!is_dir($dirname."/".$file))unlink ($dirname."/".$file); else DELETE_RECURSIVE_DIRS($dirname."/".$file); } } closedir($dir_handle); rmdir($dirname); return true; } } } ?> Hi, I am using a separate class for all the functions. And using using the following function "objectToArray" to convert the JSON decoded object to Array. Class file: class xyz { . . . . . function objectToArray($d) { if (is_object($d)) { $d = get_object_vars($d); } if (is_array($d)) { return array_map(__FUNCTION__, $d); } else { return $d; } } . . . } Main page: $obj = new xyz(); $arr = $obj->objectToArray($json_obj); Because the function "objectToArray" is recursive, array_map(__FUNCTION__, $d) is not able to applies the callback. And throws the warning "array_map() expects parameter 1 to be a valid callback". Need help! Girish I have a function that searches first for a line in a file and then for a string in that line. If the string is not found, it concatenates the line with the next line and so on until it finds the string. The following script works but it is time consuming. I want to put a "break" somewhere so that if the line is found, the foreach will break. Can someone please help and tell me how to do this? If I put the break before the recursive call, it wont do the call. If I put it after, it wont get to the break. Thanks! function findEndTag($file, $line, $consolidatedLine) { $endTagFound = strstr($consolidatedLine,"/>"); if (!$endTagFound) { $fileContent = file($file); foreach ($fileContent as $i => $lineArray) { if ($lineArray == $line) { $consolidatedLine = $consolidatedLine." ".$fileContent[$i+1]; return (findEndTag($file, $fileContent[$i+1], $consolidatedLine)); } } } else { return $consolidatedLine; } } Hey all! I'm writing a simple script to scan a local directory named 'files' and all sub directories of 'files', adding each file to a database in the same table. To do this, I'm using scandir on the current working directory/files to start, and iterating over each file in a loop, but if the file is a directory, I append the directory name to the cwd/files and call scandir on that, creating a list of files in the subfolder, and then I call my addFiles() function recursively, with this as the argument. As of now, it just stops at the second call to addFiles. It adds all the top level files fine, stops there. That's where all my print_r() lines have gotten me. Here's my code... <!-- To change this template, choose Tools | Templates and open the template in the editor. --> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title></title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> </head> <body> <?php include 'DBConnect.php'; $db = new DBConnect() or die("Can't connect to DB"); $conn = $db->getConn(); mysql_select_db('download', $conn) or die("Can't select DB"); $dir = getcwd(); $dir = $dir . '\files' . "\\"; $fid = 1; $dir = addslashes($dir); $files = scandir($dir); echo $fid . " "; echo $dir; function addFiles($files) { global $dir; global $conn; global $fid; unset($files[0]); unset($files[1]); print_r($files); foreach ($files as $aFile) { if (is_file($dir.$aFile)) { echo "<li> $aFile </li>"; $query = "INSERT INTO files (file_id, file_path, file_name) values ($fid, '$dir', '$aFile')"; mysql_query($query, $conn) or die("Something wrong with query"); $fid = $fid + 1; } else if (is_dir($dir.$aFile)) { $fid = $fid + 1; $aDir = $dir . $aFile . "\\"; echo $dir; addFiles(scandir($dir.$aFile)); } } } addFiles($files); ?> </body> </html> Thanks in advance for any ideas. Also, if I'm approaching this problem completely wrong, let me know! I just came up with this and I feel like it should work... Hey there I just started out with PHP so it might be a trivial problem. I want to populate an array with values by a recursive function but i don't get it the way i want it to have. Target array (written in python syntax):
myArray = {
key : [
[a1, a2, a3, a4],
[b1, b2, b3 ,b4]
],
key2 : [
[c1, c2, c3, c4],
[d1, d2, d3, d4]
]
}
So far i created a recursive function to collect all data i need for the array but i don't get the right syntax to achieve my target array. What i have so far is following code (snippet):
function get_data($main_dir, $items=[], $myArray=[], $depth=0) {
global $items;
if ($myArray == NULL && depth == 0) {
$myArray = array();
}
$depth++;
$dirHandle = opendir($main_dir);
while ($file = readdir($dirHandle)){
if(is_dir($main_dir.$file) && $file != "." && $file != "..") {
$new_dir = $main_dir.$file."/";
$items = get_data($new_dir, $items, $myArray, $depth);
$myArray = $items[1]
$items = $items[0]
}
else {
splitted_dir = preg_split("/\//", $main_dir);
key = splitted_dir[2];
file_information = read_out_file($main_dir.$file);
information_1 = file_information[0];
information_2 = file_information[1];
myArray = array_merge($myArray, array($key, array($key, $information_1, $information_2, $main_dir, $file))
}
}
}
The array contains all informations i need but the structure of it is not useable. Current output: Array ( [0] => key1 [1] => Array ( [0] => key1 [1] => information_1 [2] => information_2 [3] => ./path/ [4] => filename ) [2] => key1 [3] => Array ( [0] => key1 [1] => information_1 [2] => information_2 [3] => ./path/ [4] => filename ) [4] => key1 [5] => Array ( [0] => key1 [1] => information_1 [2] => information_2 [3] => ./path/ [4] => filename ) [6] => key2 [7] => Array ( [0] => key2 [1] => information_1 [2] => information_2 [3] => ./path/ [4] => filename ) [8] => key2 [9] => Array ( [0] => key2 [1] => information_1 [2] => information_2 [3] => ./path/ [4] => filename ) ) 1 ## IDK why this "1" at the end gets printed out... But what i want to get is this:
Array (
[key1] => Array (
Array (
[0] => key1
[1] => information_1
[2] => information_2
[3] => ./path/
[4] => filename )
)
Array (
[0] => key1
[1] => information_1
[2] => information_2
[3] => ./path/
[4] => filename )
)
)
[key2] => Array (
Array (
[0] => key2
[1] => information_1
[2] => information_2
[3] => ./path/
[4] => filename )
)
Array (
[0] => key2
[1] => information_1
[2] => information_2
[3] => ./path/
[4] => filename )
)
)
)
At the end i want to sort the output by alphabetic order of the keys which i should achieve with sort() i guess?
Greetings Edited August 10, 2019 by Sandy_85I need to create a function that lists subfolders of a given folder, that contain at least one .txt file. I found the following function, which displays a list of file that match a pattern in a directory tree: function find($dir, $pattern){ $dir = escapeshellcmd($dir); $files = glob("$dir/$pattern"); foreach (glob("$dir/{.[^.]*,*}", GLOB_BRACE|GLOB_ONLYDIR) as $sub_dir) //look in subdirectories { $arr = find($sub_dir, $pattern); //recursive call $files = array_merge($files, $arr); // merge array with files from subdirectory } return $files; } $txtFiles=find("project/sys","*.txt"); foreach ($txtFiles as $txtFile) { echo '<h2>'.$txtFile.'</h2>'; //display all text files } My question is, how do I change the function to return only folders that contain at least one text file. But, the functions should look inside child folders of "project/sys" and list a child folder only once if that folder or any of its child folders contain at least one text file. I'll give an example of the output I'm looking for: Folder list project/sys/diagram project/sys/bin project/sys/scripts project/sys/styles project/sys/meta The above folders may not contain a text file directly, but their children folders do. However, I'm not interested in their children folder and I want to list the above level folder only once for each folder. Thanks in advance Hi all, Ok, simple question... just imagine a multidimensional array, array(array(1,2,3,array(4,5,6, array(7,8,9)))); how to build a recursive function that will unpack all the arrays into 1 array. Somehow, none of my tries has worked out properly Cheers Hi, I am trying to recursively build another array based on the one I get back from our CRM api. The array I get back looks like this: Code: [Select] [1] => stdClass Object ( [description] => Description Text [label] => Product [name] => Product [sobject] => KnowledgeArticleVersion [topCategories] => stdClass Object ( [childCategories] => Array ( [0] => stdClass Object ( [childCategories] => Array ( [0] => stdClass Object ( [childCategories] => Array ( [0] => stdClass Object ( [label] => Apple [name] => Apple ) [1] => stdClass Object ( [label] => Orange [name] => Orange ) [2] => stdClass Object ( [label] => lemon [name] => lemon ) ) [label] => Templates [name] => Templates ) [1] => stdClass Object ( [label] => Connector [name] => Connector ) [2] => stdClass Object ( [label] => AeroView [name] => AeroView ) ) [label] => AeroWare [name] => AeroWare ) [1] => stdClass Object ( [label] => BackOffice [name] => BackOffice ) [2] => stdClass Object ( [label] => OutWare [name] => OutWare ) [3] => stdClass Object ( [childCategories] => Array ( [0] => stdClass Object ( [label] => ERA [name] => ERA ) [1] => stdClass Object ( [label] => Kairos [name] => Kairos ) ) [label] => InWare [name] => InWare ) ) [label] => All [name] => All ) ) The child categories could be any level deep. I would like put it in an array something like this: Code: [Select] Array ( [label] => Cat 1 [level] => 0 [children] => Array ( [label] => Sub Cat 1 [level] => 1 [children] => Array ( [label] => Sub Sub Cat 1 [level] => 2 ) ) ) I have tried so many things but I just can't get it right. Any assistance would be greatly appreciated. Thanks Peter I'm trying to return to array of letters that bruteForce finally decides upon. However, I can't seem to pass the array to librarySolve. I'm feeling dumb, any help? Code: [Select] function librarySolve($string){ $temp = $this->bruteForce($string, FALSE, 0); return $temp; } function bruteForce($string, $state, $trys){ $base = $string; $state = $state; $new_letters = array(); if($trys <= 6000){ $this->new_letters = $this->generateRandomCipher(); $string = preg_replace('/[^a-zA-Z0-9-\s]/', '', $string); for($a=0;$a<=strlen($string);$a++){ $letter = substr($string, $a, 1); $pattern = "/[A-Z]/"; if(preg_match($pattern, $letter)!=0){ $new_letter = $this->new_letters[$letter]; } else if(preg_match($pattern, $letter)==0) { $new_letter = $letter; } $decipher .= $new_letter; } $word_array = explode(" ", $decipher); $count = 0; for($a=0;$a<count($word_array);$a++){ $do = $this->checkWord($word_array[$a]); if(!empty($do)){ $count++; } } if($count>=2){ $state = TRUE; } else { $state = FALSE; } if($state==TRUE){ return $this->new_letters; } else { $trys++; $this->bruteForce($base, $state, $trys); } } } Can anyone suggest a solution? Code: [Select] function getOtherProject($worker) { $query2 = "SELECT company_project FROM projects WHERE username='$worker'"; $res = mysql_query($query2); while($a = mysql_fetch_array($res)) { echo "company_project = '".$a["company_project"]."' or "; } } getOtherProject($session->username); When called here reads: company_project = 'HTML' or company_project = 'Coder' or $query1 = "SELECT username, company, company_line_manager, firstname, lastname, level FROM work_users WHERE level = '4' and "; $query2 = getOtherProject($session->username); $query3 = "company_project = 'abc123'"; $query = $query1.$query2.$query3; $res = mysql_query($query, $cid); echo $query; [/code] When called here the function getOtherProject, get ignored: SELECT username, company, company_line_manager, firstname, lastname, level FROM work_users WHERE level = '4' and company_project = 'abc123' I'm new to function and I can't figure how to update/result the score. I developed a game called Rock, Paper, & Scissors, so I can learn the function itself with a simple game for now. http://pastebin.com/9MB7ATnt Any tips or instruction would be much appreciated. Thanks. Hello, New to PHP and trying to loop through rows to and get the name of the "property" in this case. I have tried foreach and while and neither seem to want to return all rows by calling the function. Does it have something to do with echo'ing the table structure or can I not return an array out of a function like this? I commented out the while loop as that wasn't working and put in a foreach loop though that didn't return all the data either. Any help is greatly appreciated Code: [Select] <?php function getProperties(){ $sql = "SELECT propertyName FROM properties;"; $result = mysql_query($sql); //$count = mysql_num_rows($result); $property = mysql_fetch_array($result); foreach($property as $propertyName){ echo "<td width=\"157\" height=\"24\" valign=\"middle\"><div align=\"left\"><input type=\"checkbox\" name=\"$propertyName\" \"id=\"$propertyName\" />$propertyName</div></td>"; } /* for($i=0;$i>=$count;$i++){ while($property = mysql_fetch_array($result)){ $propertyName = $property['propertyName']; echo "<td width=\"157\" height=\"24\" valign=\"middle\"><div align=\"left\"><input type=\"checkbox\" name=\"$propertyName\" \"id=\"$propertyName\" />$propertyName</div></td>"; } } */ } ?> I've been hacking at this for about 4 hours now..

Hello, I have been developing a website that needs to display products online, I was originally going to hand-write the PHP code but I thought it would be more beneficial to make it database orientated as new products can easily be added and a search function becomes possible. I have it working so far so good, but the last part I can't seem to get working. I have it so all the products that have the desired category are displayed, but I want a more detailed analysis of the product to appear when the image is clicked, which at the moment, displays a blank page. http://www.webwib.co...?p=floorpuzzles - this is the hand coded version that demonstrates how I want it to work. http://www.webwib.co...hp?floorpuzzles - this is the db version so far, it works how it is intended to apart from the last stage, which returns as a blank page rather than a dedicated page for the selected product.

Hi consider I have following type of directory structure inside /root folder1 -fileName1.1 -folder1.2 --fileName1.2.1 $dirItr = new RecursiveDirectoryIterator('/root'); $itr = new RecursiveIteratorIterator($dirItr); $structure ; // the type of structure i want to build store inside it foreach($itr as $object) { //magic happens here } //in the end I want folowing type of structure $structure = array('label'=>'folder1','children'=>array(array('label'=>'fileName1.1'),array('label'=>'folder1.2','children'=>array(array('label'=>'fileName1.2.1'))))); Importan observations; a)children key is an array which contains arrays of other folder or filename; b) filename does not have children attribute because they are leafs of tree c) a folder without any files will be represented as array('label'=>'emptyFolderName',children=>array()) ; //children attribute with empty array. I wd be really thankfull to the user whoever solved this problem , wasted a month already on it !! thanks in Advance. Hi all !
I have a piece of code he
$result = display_all(fcon, $var1, $var2); function display_all( // defined in another file $query = "SELECT one, two, three four, index1, index2 FROM numbers WHERE index1 = $var1 LIMIT 0, 1"; $result = mysqli_query($fcon, $query); return ($result); )and then I use the returned variable $result to display the value as follows:-
while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC))
{
echo "<tr>";
echo "<td>".$one."</td>";
echo "<td>".$two."</td>";
echo "<td>".$three. "</td>";
echo "<td>".$four. "</td>";
echo "<td>".$index1. "</td>";
echo "</tr>";
}
and this displays the n rows of data returned.
Now I have started using prepared statements and the function is now
function display_all{
$query = "SELECT one, two, three four, index1 FROM numbers WHERE index1 = ?
LIMIT 0, 10";
$stmt = $conn->prepare($query);
$stmt->bind_param('i',$var)
if($stmt->execute())
{
$stmt->bind_result($one, $two, $three, $four, $index1);
$stmt->store_result();
}
return($stmt);
}
However the returned $stmt object is unable to display the n rows of data since it shows null values. I assume that this is not the right way to use the $stmt object to display data. I must be missing something. So I request you guys to help me with this.
Thanks loads.

I will try to explain the best as i can : I have an html form and inside of that form i have a "select a state" option: Code: [Select] <select name="State"> <option value="0" selected="selected">Select a State</option> <option value="AL">Alabama</option> <option value="AK">Alaska</option> <option value="AZ">Arizona</option> <option value="AR">Arkansas</option> etc..... </select> When the customer selects a state and then clicks the forms submit button, i want them to get taken to a csv file. Inside of the csv file i have this Code: [Select] state, ip AL,67.100.244.74 AK,68.20.131.135 AK,64.134.225.33 etc....... My goal is to collect the state they choose in the html file and bring it to this csv file. Once it comes to the csv file it chooses an ip address according to the state they choose, then that ip address is sent to me in an email with the rest of the form information. So an example would be: customer fills out the html form and selects Alabama as a state. they then submit the form and the form comes to the csv file where it sees the state Alabama (AL). it then collects the ip and submits that to my email address along with the rest of the html form information (name,email,etc...). It also needs to randomly choose an ip from Alabama because in the csv file i have Alabama (AL) multiple times, so i just chooses anyone of the Alabama ip's I hope i am making sense Thanks for all your help Ali |
