Application Error in function structure, blank page result ?

Good day to you all,
here I'm trying to add to a listing directory code, another piece of code that send the list result to an html page.

It's seems like the "sending to the other page code never get executed ?

I always have this function proble can somebody so me my mistake !


Here is my code :

PHP Code:



<?php

error_reporting
(E_ALL);
ini_set("display_errors""on");

         
set_time_limit(0);
        
$directory "Art/";


function 
dirList ($directory)
{
 
    
//create 2 arrays - one for folders and one for files
   
$folders = array();
   
$files = array();
 
    
// create a handler for the directory
    
$handler opendir($directory);
 
    
// keep going until all files in directory have been read
while (false !== ($file readdir($handler))) {  
 
        
// if $file isn't this directory or its parent,
        // add it to the results array
        
if ($file != '.' && $file != '..')
       
        
// If file is directory, mark it in bold.

       
if(is_dir($directory.$file)) {
        
array_push($folders,$file);
        
            if (
time() - filemtime($directory.$file) < 604800) {
    
$folder_modified[] = "<span style=\"color:#DB1212;\"><li><div class=\"folder\"><img src=\"plus_icon.gif\"  onclick=\"Toggle('".preg_replace('/\//','_',$directory."".$file)."'); return false;\" /><b>".$file."</b></div>";
} elseif (
time() - filemtime($directory.$file) < 31556926) {
    
$folder_modified[] = "<span style=\"color:#003366;\"><li><div class=\"folder\"><img src=\"plus_icon.gif\"  onclick=\"Toggle('".preg_replace('/\//','_',$directory."".$file)."'); return false;\" /><b>".$file."</b></div>";
} else {
$folder_modified[] = "<span style=\"color:#000000;\"><li><div class=\"folder\"><img src=\"plus_icon.gif\"  onclick=\"Toggle('".preg_replace('/\//','_',$directory."".$file)."'); return false;\" /><b>".$file."</b></div>";}
 
        
       
        
// Else not styled
        
}else{
        
array_push($files,$file);
     
$filenamecor substr($file0, -4);
    if (
time() - filemtime($directory.$file) < 604800) {
    
$file_modified[] = '<span style="color:#DB1212;">'.$filenamecor.'<span>';
} elseif (
time() - filemtime($directory.$file) < 31556926) {
    
$file_modified[] = '<span style="color:#003366;">'.$filenamecor.'<span>';
} else {
$file_modified[] = '<span style="color:#000000;">'.$filenamecor.'<span>';}
 
 
    }
    }

$output "";

    
$output .= "<ul id=\"".preg_replace('/\//','_',substr($directory,0,strlen($directory)-1))."\">\n"//start a new unordered list for every iteration through dirList
 
$dircor $directory;
    
// tidy up: close the handler
    
closedir($handler);
    foreach(
$folders as $folder=>$file) {
        
      
$output .= "<li><div class=\"folder\">".$folder_modified[$folder]."</div>"//echo the folder name enclosed in a list item
        
dirList($directory.$file.'/'); //loop through the contents of $folder
      
$output .= "</li>\n"//close this list item after all files and folders in $folder have been looped through
   
   
    
}
 
    foreach(
$files as $key=>$file) {

      
$output .= "<li><a href=\"index.html\" onclick=\"load('image_view.php?dir=".$dircor."&file=".$file."','boxdisp');return false;\">&nbsp;".$file_modified[$key]."</a></li>\n"//echo the file name enclosed in a list item
    
}
 
 
    
$output .= "</ul>\n"//close the unordered list

      
return $output;

$filename 'menu.html';
// Let's make sure the file exists and is writable first.
if (is_writable($filename)) {

    
// In our example we're opening $filename in append mode.
    // The file pointer is at the bottom of the file hence
    // that's where $somecontent will go when we fwrite() it.
    
if (!$handle fopen($filename'a')) {
         echo 
"Cannot open file ($filename)";
         exit;
    }

    
// Write $somecontent to our opened file.
    
if (fwrite($handle,$output) === FALSE) {
        echo 
"Cannot write to file ($filename)";
        exit;
    }

    echo 
"Success, wrote () to file (".$filename.")";

    
fclose($handle);

} else {
    echo 
"The file ".$filename." is not writable";
}

}
    

dirList ($directory);
    




?>
the result of this is a blank page.


Thanks !
