Hello,

I need a little help with PHP.

Does anybody know how I would use the script below?

Thank you

# UL Tree----------------------------------------------------#

function SetDirTree($MultiArray,$depth=-1,$stack=0)
{
   foreach($MultiArray as $k=>$v)
       {                
       if (is_array($v))
           {
           $depth++;

           if ($olddepth!=$depth)    
               {
               $stack++;
               echo "\n".'<ul>';
               }

           if ($element>0) echo '</li>';

           echo "\n".'<li>'.$k.'';

           $element++;            
           $olddepth = $depth;

           SetDirTree($v,$depth,$stack);

           $depth--;            
           }
       }
   
       if ($depth!=$stack) echo '</li></ul>';
}

echo '<ul>';
SetDirTree($testlist);

Looks like it makes an unordered list out of an array but I could be wrong.

Thanks for getting back to me.

I can see that but what I was wondering how I would pass the array to that script.

What I’m basically looking for is a script that would show my directory structure in a clean unordered list.

If I pass the following to the list script, it doesn’t work.

<?php

// $path : path to browse
// $maxdepth : how deep to browse (-1=unlimited)
// $mode : "FULL"|"DIRS"|"FILES"
// $d : must not be defined
   
function searchdir ( $path , $maxdepth = -1 , $mode = "FULL" , $d = 0 )
{
   if ( substr ( $path , strlen ( $path ) - 1 ) != '/' ) { $path .= '/' ; }        
   $dirlist = array () ;
   if ( $mode != "FILES" ) { $dirlist[] = $path ; }
   if ( $handle = opendir ( $path ) )
   {
       while ( false !== ( $file = readdir ( $handle ) ) )
       {
           if ( $file != '.' && $file != '..' )
           {
               $file = $path . $file ;
               if ( ! is_dir ( $file ) ) { if ( $mode != "DIRS" ) { $dirlist[] = $file ; } }
               elseif ( $d >=0 && $d < $maxdepth )
               {
                   $result = searchdir ( $file . '/' , $maxdepth , $mode , $d + 1 ) ;
                   $dirlist = array_merge ( $dirlist , $result ) ;
               }
       }
       }
       closedir ( $handle ) ;
   }
   if ( $d == 0 ) { natcasesort ( $dirlist ) ; }
   return ( $dirlist ) ;
}

?>

Maybe

$path = "assets/images/";
setDirTree(searchdir($path));

I add a few lines at the bottom and it works.

<?php

// $path : path to browse
// $maxdepth : how deep to browse (-1=unlimited)
// $mode : "FULL"|"DIRS"|"FILES"
// $d : must not be defined

function searchdir ( $path , $maxdepth = -1 , $mode = "FULL" , $d = 0 )
{
if ( substr ( $path , strlen ( $path ) - 1 ) != ’/’ ) { $path .= ’/’ ; }
$dirlist = array () ;
if ( $mode != "FILES" ) { $dirlist[] = $path ; }
if ( $handle = opendir ( $path ) )
{
while ( false !== ( $file = readdir ( $handle ) ) )
{
if ( $file != ’.’ && $file != ’..’ )
{
$file = $path . $file ;
if ( ! is_dir ( $file ) ) { if ( $mode != "DIRS" ) { $dirlist[] = $file ; } }
elseif ( $d >=0 && $d < $maxdepth )
{
$result = searchdir ( $file . ’/’ , $maxdepth , $mode , $d + 1 ) ;
$dirlist = array_merge ( $dirlist , $result ) ;
}
}
}
closedir ( $handle ) ;
}
if ( $d == 0 ) { natcasesort ( $dirlist ) ; }
return ( $dirlist ) ;
}

// Make a nice list of the current directory
echo "<ul>";
foreach (searchdir(".") as $v) {
echo "<li>".$v."</li>\n";
}
echo "</ul>";

?>

this seems to work now:

<?php

     if ( !is_string($path) or !($style==0 or $style==1) ) die("Improper arguments in function dirTreeToArray(string \$path, \$style = {0, 1})"); 
     else {
        $path = trim($path);
        $path = str_replace("\\", "/", $path);
        if( '/' == $path{strlen($path)-1} || '\'' == $path{strlen($path)-1} ) $path = substr($path, 0, strlen($path)-1); 
     }
     $tree = array();
     $arrayPointer = & $tree;
   if ( $handle = opendir($path) ) {
       while ( $fileName = readdir($handle) ) {
             if ( $fileName != "." and $fileName != ".." ) { 
                       $newPath = "$path/$fileName";        // Used for testing directory or file property
                 if ( is_dir($newPath) ) {
                   $dummyPointer = & $arrayPointer;        // Save the current pointer 
                     if ( $style == 0 ) $arrayPointer = & $arrayPointer[$fileName];    // Drop the pointer into a subdirectory
                     elseif ( $style == 1 ) $arrayPointer = & $arrayPointer[];        // Drop the pointer into a subdirectory 
                     $arrayPointer = dirTreeToArray($newPath, $style);            // Process the new subdirectory
                   if ( $style == 1 ) sort($arrayPointer);    // Sort it if we're in a non-associative mode 
                     $arrayPointer = & $dummyPointer;        // Bring the pointer back up a level
               }
                 //elseif ( is_file($newPath) ) $arrayPointer[] = $fileName;    // Enter the files 
           }
       }
               return $tree;
   }
   else die("Failed to open directory $path in function dirTreeToArray(string \$path, \$style = {0, 1})");
}
