Why the file cannot be read? The permissions of the path pdf file have been set

<code>$PDF = './22.pdf';

$IM =new imagick();
   $IM->setResolution(120,120);
   $IM->setCompressionQuality(100);
   $IM->readImage($PDF);
   foreach($IM as $Key => $Var){
       $Var->setImageFormat('png');
       $Filename = './'.md5($Key.time()).'.png';
       if($Var->writeImage($Filename)==true){
           $Return[]= $Filename;
       }
   }
</code>
