How can one check to see if a remote file exists using PHP?

Question

The best I could find, an if fclose fopen type thing, makes the page load really slowly.

Basically what I\'m trying to do is

Answer 1

To check for the existence of images, exif_imagetype should be preferred over getimagesize, as it is much faster.

To suppress the E_NOTICE, just prepend the error control operator (@).

if (@exif_imagetype($filename)) {
  // Image exist
}

As a bonus, with the returned value (IMAGETYPE_XXX) from exif_imagetype we could also get the mime-type or file-extension with image_type_to_mime_type / image_type_to_extension.
