benn_jgh Posted April 15, 2006 Share Posted April 15, 2006 I'm trying to check if an external image exists. Although there are already several ways to do this in PHP (getimagesize(), fopen() etc), none of these ways are near fast enough. I posted this in the hacking section because I need a very clever way to quickly check whether or not an image exists and I know there isn't a standard function for this.Thanks Link to comment https://forums.phpfreaks.com/topic/7484-check-if-external-image-exists/ Share on other sites More sharing options...

I dont think your going to get much quicker than getimagesize(), but you might start by looking at the code for that.You do know C right?

ccm84 Posted May 2, 2006 Share Posted May 2, 2006 I'd believe file_exists() is faster. Link to comment https://forums.phpfreaks.com/topic/7484-check-if-external-image-exists/#findComment-32690 Share on other sites More sharing options...
