PHP - Longest String In Arrays
Hi
I've written a function which should reference a couple of arrays, and return an array of the length of the longest value in the arrays. Confused, let me explain some more. Code: [Select] <?php function getLongest($records,$headers){ foreach ($headers as $fieldid){ foreach($records as $recordid){ $length[]=strlen(getContent($fieldid,$recordid)); } $result[$fieldid]=max($length); } return $result; } ?> I pass in 2 arrays, the first ($records) being references to the record id's from my DB, the second ($headers) is the column from my DB table where I pull the record info from. I have another function getContent which cross references these 2 values and gets the actual data (this works fine) I am trying to create an array of every content entry for each heading, then iterate through it and find the longest value. Then return an array of heading reference against longest content length. My content varies between 10 characters to a couple of hundred characters long, dependant on the column. I have approx 3000 entries in the DB. The results I'm getting are just not what I'd expect, i.e, I run the function against columns showing longtitude and latitude of locations, (expect the result to be approx 12 for the longest) but I get 38?!?! I've even tried using trim() with it incase there's any leading / trailing whitespace. Any thoughts? Similar TutorialsI have a really weird thing that I have to do, and I can't figure it out. I've tried about 1 million nested loops, and just can't get this to work. What I need to do is get the longest number from a string. So, for example, take the following: $string = "asdfasd234kjljlkjlj34659823423sadfasdadasdfasdfas d3242sdasddsda2"; function getNumber($a) { //do something with $string and return the longest number from it } so that ... echo getNumber($string); will return '34659823423' Thanks in advance, fellas! I've really been racking my brain there. Hiya! I have a file (see attached) that contains basic HTML for a page with multiple paragraphs. How do I check the length of each paragraph to find out if it is 30 characters or over? If the first paragraph is not equal to 30 characters, then it should move on to the next one, and so on. If a paragraph is found to be the correct length, I then need to extract the text from the <p> tags. If a none of the paragraph match 30 characters in length, then the code will need to choose the best length paragraph. Any help is greatly appreciated. Many Thanks, FishSword I have this thing that i am trying to make but i cant get it to work.. can anyone help? Code: [Select] function sql_read( $dbname,$dbusername,$dbpassword ) { $names = array(); $password = array(); $connect = @mysql_connect("mysql11.000webhost.com",$dbusername,$dbpassword) or die("Could Not Connect"); @mysql_select_db ($dbname) or die("Could not find DataBase"); $query = mysql_query("select * from users"); $numrows = mysql_num_rows($query); if ($numrows > 0){ while($row = mysql_fetch_assoc($query)){ $names[] = $row["uname"]; $password[] = $row["password"]; $id = $row["id"]; } $return = array($names,$password,$id); }else{ $return = array(); } return $return[]; } $names = array(); $names = sql_read("XXXXXX","XXXXXX","XXXXXXX")[0]; The error i get is Code: [Select] Parse error: syntax error, unexpected '[' in /home/a5480952/public_html/sql/index.php on line 28 Line 28 is "$names = sql_read("XXXXXX","XXXXXX","XXXXXXX")[0];" Please help... i REALLLLD need help with this.. ask questions if you want to know more about what i am trying to do... thanks! I'm having troubling with trying to create a function to spit out a single array with the following array. I can write it in a away that looks through the arrays manually. the results i am trying to generate is that each item in generated array. Array to convert array( "account" => array( "login", "register", "logout", "edit", ), "p" => array( "report", ), "array1.0" => array( "array2.0" => array( "array3.0", "array3.1 ), "array2.1", ), generating the array will look like this
Array ( [0] => account [1] => account/login [2] => account/register [3] => account/logout [4] => account/edit [5] => p [6] => p/report [7] => array1.0 [8] => array1.0/array2.0 [9] => array1.0/array2.0/array3.0 [10] => array1.0/array2.0/array3.1 [11] => array1.0/array2.1 ) The idea is that id generates a single array with combined labels and arrays inside, etc. I just can't figure out how to create a script that will create this array even If I add a new value or array.
I have two arrays, both with the same key values. I'd like to combine them. So for instance... Code: [Select] <?php $array1['abcd'] = array( 'value1' => "blah", 'value2' => "blahblah"); $array1['efgh'] = array( 'value1' => "ha", 'value2' => "haha", 'valuex' => "xyz"); $array2['abcd'] = array('value3' => "three", 'value4' => "four"); $array2['efgh'] = array( 'value3' => "hohoho", 'value6' => "six6"); function combine_arrays($array1,$array2) { //*combining* return $single_array; } echo "<pre>"; print_r(combine_arrays($array1,$array2)); echo "</pre>"; /* would produce ['abcd'] = ( 'value1' => "blah", 'value2' => "blahblah", 'value3' => "three", 'value4' => "four" ) ['efgh'] = ( 'value1' => "ha", 'value2' => "haha", 'valuex' => "xyz", 'value3' => "hohoho", 'value6' => "six6" ) */ ?> What's the easiest way to do this? Hi, I am trying to make some adjustments to uploadify.php which comes with the latest version of uploadify (3.0 beta), so that it works with a session variable that stores the login username and adds it to the path for uploads. Here is uploadify.php as it currently looks: Code: [Select] <?php session_name("MyLogin"); session_start(); $targetFolder = '/songs/' . $_SESSION['name']; // Relative to the root if (!empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder; $targetFile = rtrim($targetPath,'/') .'/'. $_FILES['Filedata']['name']; // Validate the file type $fileTypes = array('m4a','mp3','flac','ogg'); // File extensions $fileParts = pathinfo($_FILES['Filedata']['name']); if (in_array($fileParts['extension'],$fileTypes)) { move_uploaded_file($tempFile,$targetFile); echo '1'; } else { echo 'Invalid file type.'; } } echo $targetFolder; ?> I added Code: [Select] echo $targetFolder; at the bottom so that I could make sure that the string returned was correct, and it is, i.e. '/songs/nick'. For some reason though, uploads are not going to the correct folder, i.e. the username folder, but instead are going to the parent folder 'songs'. The folder for username exists, with correct permissions, and when I manually enter Code: [Select] $targetFolder = '/songs/nick';all works fine. Which strikes me as rather strange. I have limited experience of using php, but wonder how if the correct string is returned by the session variable, the upload works differently than with the manually entered string. Any help would be much appreciated. It's the last issue with a website that was due to go live 2 days ago! Thanks, Nick Hello all, I'm trying to change the end of a javascript call based on the end of the url string. The common part of all the url strings is sobi2Id=, I'm trying to do this with strstr but am having no luck. I'm new to php so my syntax knowledge is terrible! at the moment i've got Code: [Select] <?php $url = $_SERVER['REQUEST_URI']; $tag = strstr ($url, 'sobi2Id='); echo $tag; ?> but this returns an unexpected T_STRING, expecting ',' or ';' Can anyone debug this? I may well be being really silly! Hey there, Thanks for taking the time to read my thread. My issue is that I can't think of a way to edit a XML file using PHP's XML functionality and then assign the edited contents to a string instead of saving the file. Because my issue is that I have to edit the XML file based upon a string brought from a remote location then give it back to that remote location using a string again, to be exact I am doing it via Linux command line utilizing SSH2. This is what I managed to complete on my own. function CheckIVMPConfig($ServerID) { global $Panel; if(is_numeric($ServerID) && $this->IsValidServer($ServerID)) { // We select the game server that the FTP account was created for. $Servers = mysql_query("SELECT * FROM control_servers WHERE server_id = '".mysql_real_escape_string($FTPAccount['ftp_server'])."'"); $Server = mysql_fetch_array($Servers); // Here we select the Box ID that the game server is on. $Boxs = mysql_query("SELECT * FROM control_machines WHERE machine_id = '".$Server['server_machine']."'"); $Box = mysql_fetch_array($Boxs); // Now we select the required package for the box. $Packages = mysql_query("SELECT * FROM control_packages WHERE package_id = '".$Server['server_package']."'"); $Package = mysql_fetch_array($Packages); // Retrive the file. $Config = $CProtocol->exec("cat /home/{$Server['server_id']}/{$Package['package_config']}"); $Parse = SimpleXMLElement($Config); foreach($Parse as $Entry) // loop through our books { if($Entry->port != $Server['server_port']) { // edit the value } else if($Entry->maxplayers > $Server['server_slots']) { // edit the value } } } } This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=326004.0 I have the following function, which takes a string with commas in it and attempts remove those commas. The way I have it here is that I use explode to take out the commas, which makes an array, and then iterate through that array to put a string back together without the commas. function tags_to_sort_by( $sortMeta ) { $sortByArray = explode(",", $sortMeta); $sortByCount = count($sortByArray); for ($i = 0; $i < $sortByCount; $i++) { $sortByString += $sortByArray[$i]; } return $sortByString; } What does not work is the following line: $sortByString += $sortByArray[$i]; Somehow that outputs a 0, which I don't understand. It should output something like: arrayItem1 arrayItem2 array3 etc. My question is if there either is an easier way to remove the commas from the original string or what I am doing wrong in this line: $sortByString += $sortByArray[$i]; // I am trying to concatenate each part of the array back into the string. Thanks a lot for help with this! hey guys im trying to find a string inside a string which could be made up of different things eg... {$test}, {$test1}, {$test2} etc (but the varable inside could be called anything hence maybe using regex im not sure?) is this possible?...i hope you guys understand....thanks
In PHP Version 8.0 shows error as : In previous versions of PHP it does not show any error. Please resolve the issue. I am looking for a date within larger string, lets say the date is December 4, 2010. To find it I use pattern and function below: $Pattern='/[(January|February|March|April|May|June|July|August|September|October|November|December)] \d, \d\d\d\d/i'; preg_match_all($Pattern, $String, $Matches, PREG_OFFSET_CAPTURE, $NumberPosition); The function finds the dates within the string but to my supprise the result I get in $Matches is: r 4, 2010 What I would like to get is: December 4, 2010 but don't know how it should be fixed. I thought that with the pattern I am using but obviously that is not the case. Hello guys i am trying to figure out how to fwrite a string for example "Recommended Settings for Service Pack" under "Current Settings for Service Pack: 5.1.2600ServicePack3Build2600". I figure i cant use line number as an argument because the file report may be dynamic so i will need to use Current Settings as an argument. Please guide me if you have any ideas..thanks:) ! auditreport table ServicePackSetting Service Pack Requirement: Fail Current Settings for Service Pack: 5.1.2600ServicePack3Build2600 MajorAuditandAccountPolicies Maximum Password Age Requirement: Fail Current Settings for Maximum Password Age Requirement: 42 Minimum Password Length: Fail Current Settings for Minimum Password Length Requirement: 0 I need to know if a string exists within a string. I've tried using STRIPOS() but it returns zero or false if what I'm looking for is the first part of the string. I don't care what function I use, but I need to get a "true" when the needle string is present anywhere in the haystack string, even at location zero. Is there some way to set up the STRIPOS() statement? I've tried: if ((stripos($title, 'needle') > 0 ) if ((stripos($title, 'needle') = true ) and even if ((stripos($title, 'needle') >= 0 ) which returns true for everything, even when the needle string is NOT present. Any help appreciated. thanks, Tom Ok... I had typed this post out ONCE already and when I clicked REFRESH IMAGE to get a diff captcha it ERASED MY POST LMAO this is not my night.... What I need help with is probably more simple then I can even think right now - ive been digging at this for 3 hrs now and im out of time for the night I have a DB Record storing ID's between PIPES | when the initial entry is made in DB it stores it like so |47| NOTE: the number could be different these are ID's number doesnt matter its just between Pipes When the second entry is added its added like so |47||67| say we have a total of 5 Entries |47||67||82||55||69| I need to find ID 82 in that string and it has to be between Pipes Find 82 in data between | and return that ID 82 I am putting between pipes because the ID's can be duplicate digits in different lengths so say I have 8 as my ID and down the string i have another id as 88 -- I cant possibly find the correct ID without some sort of seperation character so i used Pipes soo my end goal is the ability to search and if true or false do action if ($result == $find_id){ echo "ID is there"; }else{ echo "NOT THERE -- Adding it"; } Any help is appreciated guys Thanks SangrelX hey guys just a simple one...im trying to replace {$name} but i dont think ive got the right prefix in the str_replace function...if anyone could tell me where i am going wrong please $content = str_replace("{/$".$variable."}", $value, $content); {$name} Given a text value $path, I want to return the actual path. One option is a switch statement as shown below. Another option is put them in an associated array (or maybe a static array?) and check if the element is set and if not throw an deception. Or maybe a totally different solution. Is one solution better (i.e. more efficient) than another? I will probably be retrieving a path around 5 times for every server hit. Thanks
function getPath($path) { switch($path){ case 'classes': $path=__DIR__;break; case 'application': $path=dirname(__DIR__);break; case 'root': $path=dirname(dirname(__DIR__));break; case 'twig': $path=dirname(dirname(__DIR__)).'/vendor/autoload.php';break; case 'lib': $path=dirname(__DIR__).'/lib';break; case 'help': $path=dirname(__DIR__).'/lib/help'; case 'templates': $path=dirname(__DIR__).'/lib/templates'; case 'htdocs_base': $path=dirname(dirname(__DIR__)).'/html'; case 'resources_base': $path=dirname(dirname(__DIR__)).'/user_resources'; // About 10 more default: throw new Exception("Path {$path} not valid."); } return $path; } I'm trying to do some regex, but I'm having trouble with my input string for the regex. I'm querying a server and getting results from that via socket and trying to regex the results and extract content. I've got the regex working (thanks to mjdamato ), but it only works when I have the regex string like this: $input = "hostname: Hooter's GG 5.1 Elimination HLstatsX:CE version : 1.0.0.58/15 4426 secure udp/ip : 25.2.132.39:27015 map : fy_dustdm at: 0 x, 0 y, 0 z players : 0 (20 max) # userid name uniqueid connected ping loss state adr "; When I get the results from my socket it's stored in a variable and it doesn't work when it's exactly the same. I did var_dump on the results from the socket and this is what it outputs: string(229) "hostname: Hooter's GG 5.1 Elimination HLstatsX:CE version : 1.0.0.58/15 4426 secure udp/ip : 25.2.132.39:27015 map : fy_dustdm at: 0 x, 0 y, 0 z players : 0 (20 max) # userid name uniqueid connected ping loss state adr " Since it's exactly the same why doesn't the second way work? Let me know if this is too confusing.. |
