PHP - Recursive Function Not Working Correctly

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 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 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]

                    [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

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?

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

I 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

    if ($template->load($maintemplatefile,$values)) {
       //load every php file in the plugin folder

    //Handle invalid page Requests
    } else {
      echo '404 File Not Found';
      //exit;
    }

    //print page code
    echo $template->html();
  }



I call the above code it prints out the template file but it does not recursively replace the <TEMPLATE_LOADTEMPLATE_$1> that is in the file even though it properly parses both the $tag and $value variables going to the $this->replace($tag,$value); line.  Any idea why this does not work?

<?php

  class Template {
    var $code='';

    function load($file,$values) {
      if (file_exists($file)) {
        //get template directory
        $dir=substr($file,0,strrpos($file,'/')) . '/';
       

        //get template
        $this->code=file_get_contents($file);

        //check if any recurseve templates to add
        $tags=$this->tags();

        //process all internal template tags
        $newValues=array_slice($values,1);
        foreach ($tags as $tag) {

          //handle inserting new template file
          if (substr($tag,0,13)=='LOADTEMPLATE_') {
            $file=substr($tag,13);
            if ($file[0]=='$') {
              $file=$values[(substr($file,1)-1)];
            }
            $temp=new Template;
            $filename=$dir . $file . '.xhtml';
            if ($temp->load($filename,$newValues)) {
              $value=$temp->html();
            } else {
              $value='File Not Found';
            }
            $this->replace($tag,$value);
          }
        }


        return true;
      } else {
        return false;
      }
    }

    function tags() {
      preg_match_all('/<TEMPLATE_[^<]+?>/', $this->code, $tags);
      $tags=$tags[0];
      foreach ($tags as $key=>$value) {
        $tags[$key]=substr($value,10,-1);
      }
      return array_unique($tags);
    }

    function replace($tag,$value) {
      $this->code = ereg_replace('<TEMPLATE_' . $tag . '>',$value . '',$this->code);
    }

    function replaceSection($tag,$value) {
      $replace='~<TEMPLATE_' . $tag . '>[\s\S]*?</TEMPLATE_' . $tag . '>~';
      $this->code = preg_replace($replace,$value . '',$this->code);
    }

    function compress() {
      $this->code = ereg_replace("\n",'',$this->code);
      $this->code = ereg_replace("  ",' ',$this->code);
      $this->code = ereg_replace("\r",'',$this->code);
    }

    function html() {
      //remove <TEMPLATE_*> & </TEMPLATE_*> tags then return html.
      return preg_replace('/(<\/?)TEMPLATE_[^<]+?>/','',$this->code);
    }
  }

?>

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>

$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

Hello,

I am pasting code below that isn't working corrrectly. One problem is the pagination. When I get more than 10 records, it will show the next 10 link but when I click on it, it just takes me back to an empty page with NO results. How do I fix this?

Also where do I insert the block of code for a table to structure my results. As of now, the returned results are all over the page! Thanks!

This is the code:
Code: [Select]
<?php
// display what the person searched for
echo "<p>You searched for: &quot;" . $var . "&quot;</p>";

// begin to show results set
echo "Results";
$count = 1 + $s ;

// now you can display the results returned
  while ($row= mysql_fetch_array($result)) {
  $title = $row["1st_field"];

  echo "$count.)&nbsp;$title" ;
  $count++ ;
  }

$currPage = (($s/$limit) + 1);

//break before paging
  echo "<br />";

  // next we need to do the links to other results
  if ($s>=1) { // bypass PREV link if s is 0
  $prevs=($s-$limit);
  print "&nbsp;<a href=\"$PHP_SELF?s=$prevs&q=$var\">&lt;&lt; 
  Prev 10</a>&nbsp&nbsp;";
  }

// calculate number of pages needing links
  $pages=intval($numrows/$limit);

// $pages now contains int of pages needed unless there is a remainder from division

  if ($numrows%$limit) {
  // has remainder so add one page
  $pages++;
  }

// check to see if last page
  if (!((($s+$limit)/$limit)==$pages) && $pages!=1) {

  // not last page so give NEXT link
  $news=$s+$limit;

  echo "&nbsp;<a href=\"$PHP_SELF?s=$news&q=$var\">Next 10 &gt;&gt;</a>";
  }

$a = $s + ($limit) ;
  if ($a > $numrows) { $a = $numrows ; }
  $b = $s + 1 ;
  echo "<p>Showing results $b to $a of $numrows</p>";
  
?>

I'm getting the following error with the code below:

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ',' or ';' in C:\wamp\www\flow\fpdf\rev.php on line 47

Can I get another set of eyes to look at it & see what I'm missing?

This doesn't work and just echo's "sizel". Why?

I want to make it so that whoever is sending the fame (sender) doesn't send it to themselves (receiver).

However, I can't get it to block that. Everything else works, so something must be up with that specific requirement.

Any help would be appreciated!

Thanks!

Hello PHP Wizards, i wonder if anyone can help, Ive got an associative array set up with a bunch of items, the idea is to compare the array items with items from a form using $_POST.

So far ive got the items displaying from the form as follows


Code: [Select]
<?php
  while ($client_prices = each($_POST)) { /* sets the name of the array to $client_prices for easy identification */
    echo $client_prices['key']; /* Displays the keys withing the $client_prices array */
  echo ' - ';
    echo $client_prices['value']; /* Displays the values within the $client_prices array */
    echo '<br />';
  }
?>
and for the sake of it ill display the array ive set up on the server side using similar code :

Code: [Select]
<?php
while ($server_prices = each($coffee_prices)) { /* sets the name of the array to $server_prices for easy identification */
echo $server_prices['key']; /* Displays the keys withing the $server_prices array */
echo ' - ';
echo $server_prices['value']; /* Displays the values within the $server_prices array */
echo '<br />';
}
?>
now, what i want to do is make sure that the keys (name of items) and the values (cost of items) from the client side are the same as the keys and values ive set on the server. so i created an if statement :

Code: [Select]
<?php 
if(
$client_prices['key'] === $server_prices['key'] && $client_prices['value'] === $server_prices['value']
)
echo  'Prices Match';
else
echo  '<h2>Oops! Somthing Has Gone, Please Call Us To Place Your Order</h2>';

?>

so i thought i had it all working when as it came back with 'prices match', i thought all is good. however when i purposely change the value of one of the items in my server side array so it will be different from the incoming client value, it still says 'prices match' when they clearly don;t?

Anyone help would be appreciated

p.s. im fairly new to php, and this is for my learning, not a real client.

Hi, i am trying to add a very simple shopping cart script to my site, and the session is simply used to keep the contents of the shopping cart, yet its not working properly!
Ok ignoring the layout issues with the cart here is the issues.
Only two links to the same script
First one is a link to the shopping cart with an action to add the item ID to it.
http://www.heliuk.co.uk/index.php?n=pages/shop-cart-action&id=1&action=add

This works, it adds the item to the session "cart", if that's successful it then shows the cart from the session.

But if i just go to the shopping cart with no actions (so just to view it) it shows no items
http://heliuk.co.uk/index.php?n=pages/shop-cart-action

And what this is doing is checking it the cart is empty, if not show the cart, if it is then show nothing, which is what happening. But if you go back to the first link and add the item again, it is adding it on to the cart so the session is there and working? I don't understand what's happening!
Here the shopping cart page.
Code: [Select]
<?php
error_reporting(E_ALL ^ E_NOTICE);
$product_id = $_GET["id"]; //the product id from the URL
$action = $_GET["action"]; //the action from the URL

//if there is an product_id and that product_id doesn't exist display an error message
if($product_id && !productExists($product_id)) {
die("Error. Product Doesn't Exist");
}

switch($action) { //decide what to do

case "add":
$_SESSION['cart'][$product_id]++; //add one to the quantity of the product with id $product_id
break;

case "remove":
$_SESSION['cart'][$product_id]--; //remove one from the quantity of the product with id $product_id
if($_SESSION['cart'][$product_id] == 0) unset($_SESSION['cart'][$product_id]); //if the quantity is zero, remove it completely (using the 'unset' function) - otherwise is will show zero, then -1, -2 etc when the user keeps removing items.
break;

case "empty":
unset($_SESSION['cart']); //unset the whole cart, i.e. empty the cart.
