Handle error when getimagesize can't find a file

Question

when I\'m trying to getimagesize($img) and the image doesn\'t exist, I get an error. I don\'t want to first check whether the file exists, just handle the error.

Answer 1

Call me a dirty hacker zombie who will be going to hell, but I usually get around this problem by catching the warning output into an output buffer, and then checking the buffer. Try this:

ob_start();
$data = getimagesize('not-existing.png');
$resize_warning = ob_get_clean();
if(!empty($resize_warning)) {
  print "NOT OK";
  # We could even print out the warning here, just as PHP would do
  print "$resize_warning";
} else {
  print "OK"
}

Like I said, not the way to get a cozy place in programmer's heaven, but when it comes to dysfunctional error handling, a man has to do what a man has to do.
