why width and height of image is not able to get in php

Question

i am uploading image to s3 server and by php i am making a copy of that image on server , if i upload an image of 2.3 mb than the width of image is not coming but if i upload less size image like 26kb than it is showing the width of image so it is able to create the copy .

here is my code of php :

$s3 = new S3(awsAccessKey, awsSecretKey);

        $thumbId = uniqid();
        $thumbId .= ".jpg"; 
        $img = '';

        if($imgType == "image/jpeg"){
            $img = imagecreatefromjpeg($sourceUrl);
        }else if($imgType == "image/png"){
            $img = imagecreatefrompng($sourceUrl);
        }else if($imgType == "image/gif"){
            $img = imagecreatefromgif($sourceUrl);
        }else{
            $img = imagejpeg($sourceUrl);
        }

    echo    $width = imagesx( $img );
        echo $height = imagesy( $img );

please tell me what is the problem with size of image..

I can be wrong, but I am fairly sure this is a memory issue that doesn't get displayed because some aspect of error reporting is turned off.

Either that, or the 2.3 MB image is broken or in a format that GD can't read - make sure you try it with various images.

If it's a memory issue, here is a related question.
