Not sure if this is typo or not (not the most knowledgeable w/ PHP), but…

$tmpFile = $_FILES['myFile']['tmp_name']; // path of the temp file created by PHP during upload
$imginfo_array = getimagesize($tempFile); // returns a false if not a valid image file

getimagesize uses “tempFile” as its argument, while “tmpFile” was initialized above. Shouldn’t getimagesize use “tmpFile”?

This is great, I am looking for a snippet like this to ensure that the uploads are images for an upcoming project, this may do the trick nicely.

Thanks.

For images, a simpler way might be using getimagesize() which returns an array containing the mime type of the image.
