[PHP] fopen to check if file exists

2001-12-08 Thread moe 

I am using this function:

function isAfile($url){
$fp = @fopen($url,r);
if ($fp)
  { //print The file exists!;
  return 1; }
else
  { //print The file does not exist;
return 0; }
 }

to check if a remote file exists... now the problem is that the URL's i am
trying to check are in this way:
http://waptopic.supereva.it/loghiesuonerie.it/LogoGen.php?id=1100
The problem is that LogoGen.php exists but depending on the ID the image may
exists or not.
How can i actually check if the image exists?
Thanks anyone!

I've tested given url..
If there is no image php script return file = '139'.
Check if file content is different from 139.

or try to get image size of file:
$size = GetImageSize
(http://waptopic.supereva.it/loghiesuonerie.it/LogoGen.php?id=1100;);

and check what happens if there is no image
