Calling a Function from a String - error

Hi guys,

I have this:

$param = "../foldera/folderb";
delete_recursive_dirs($param);

delete_recursive_dirs() - is a function which deletes a folder and all it's contents.

When I run the code above, it throws an error, but when I run it like this:

delete_recursive_dirs("../foldera/folderb");

it works perfectly...

Any ideas on what I need to do for this to work?

Cheers!

The code as you have posted it now should work perfectly fine.

Unfortunately, it doesn't...

Anything I can try?

Using echo to display debug data.

echo '<div>'.$params.'</div>';

And possibly edit delete_recursive_dir to show debug data as well.

Tried that, doesn't work,

URL I call:

mypage.php?function=cb_deletecase&param='../Development/OwcClientFiles/19/1/1/61/358'

and here's my code if it helps?

<html>
 <head>
<?php
 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.DIRECTORY_SEPARATOR.$file))
 unlink ($dirname.DIRECTORY_SEPARATOR.$file);
 else delete_recursive_dirs($dirname.DIRECTORY_SEPARATOR.$file);
 }
 }
 closedir($dir_handle);
 rmdir($dirname);
 return true;
 }

 $function = $_GET['function'];
 $param = stripslashes($_GET['param']);
 if ($function != "") {
 $background = 'orange';
 } else {
 $background = 'green';
 }

 switch($function) {
 case "cb_deletecase":
 $background = 'blue';
 $url = delete_recursive_dirs($param);
 break;
 }
?>
 </head>
 <body bgcolor='<?php echo $background; ?>'>
 <?php
 echo "delete_recursive_dirs(".$param.")\n";
 echo "\t".$_SERVER['SCRIPT_NAME']."\n";
 echo "\t".$url."\n";
 ?>
 </body>
</html>

and this is the full error:

<html>
 <head>
