togliere un valore da una stringa

[camicio109]

se ho capito giusto

$directory="documento/uploads"; 
$open_handle=opendir($directory); 
while($read=readdir($open_handle)){ 
if($read!="." && $read!=".."[B]&& $read!='index.php'[/B]){ 

echo ("<a href=\"$read\">$read</a>"); 
echo ("<a href=\"uploadbild.php?file=$read\" title=\"cancella il file\"> - cancella</a>
"); 
} 
} 
closedir($open_handle);
