If you don't sure whether the file exists or not or maybe it's broken, then you should use try - catch construction. It prevents code fails, when code stops execution after call of pingImage (if the file doesn't exist or it's broken).



<?php

$im = new Imagick();

try {

    $im->pingImage('3.jpg');

}

catch(ImagickException $e) {

    echo "image doesn't exist";

}

?>

Actually the previous example causes file to be loaded twice on Imagick's stack, proper way to do this is:



<?php



$file = 'foo.jpg';

$image = new Imagick();

$image->pingImage($file);

$image_info = $image->identifyImage();



?>
