Question

Hey; I’m currently using the following way of checking whether an image exists on a server:

if (@getimagesize($s3url))
   { 
      //do stuff 
   }

Needless to say, that’s hardly the most elegant way of doing that… But honestly, I don’t actually know where to start looking for a better solution.

I was wondering if perhaps it was possible to just send a request, receive a HTTP response (i.e. if the HTTP response is 200, carry on, if not, evaluate to false); but is that the best way?

What is the best function to check for the existence of an (image) file?

Answer 1

file_exists() then check whether the file really is an image or not using getimagesize()
