[RESOLVED] file_exists not working

[clairence]

I just can't figure this out.

$piclocfull=$piclocprefix.$findpic[0].'-th.'.$findpic[1];
if(file_exists($piclocfull)){ // this line
    $img_display=$piclocfull;
} else{
    $img_display=$piclocprefix.'noImagelogo50.png';
}

This script returns all images as the NOIMAGE logo (opposite of what I want).

$piclocfull=$piclocprefix.$findpic[0].'-th.'.$findpic[1];
if(!file_exists($piclocfull)){  // this line 
    $img_display=$piclocfull; 
} else{
    $img_display=$piclocprefix.'noImagelogo50.png';
}

This script returns all images with the piclocfull URL, including the ones that are non-existent images, which should have become the noImage logo.

So how do I set it up so the image files that exist are displayed, and when one doesn't exist, we display the noImage logo?

Thanks for any thoughts.

Try using getimagesize if you are going to use a URL (as opposed to a local file system path) as a 404 not found (aka not existant) still returns information (namely a 404 header status and a body telling the user it wasn't found).

$piclocfull=$piclocprefix.$findpic[0].'-th.'.$findpic[1]; 
if( getimagesize($piclocfull) !== FALSE ) {
   $img_display = $piclocfull;
} else {
   $img_display=$piclocprefix.'noImagelogo50.png'; 
}

The fact that invalid URLs would result in a 404 error doesn't matter; what does matter is that [man]file_exists/man doesn't support the 'http://' wrapper as stated by the manual.
