[PHP] Checking if an image exists on a remote server.

[darthmincho@gmail.com]

Hi.
I want to check if an image exists on a remote server, and if it does,
show it. I
If it does not exist I want to show a default message. I have
previously used these chunks of code but none of them have worked. Any
Ideas?

------------------------
$imgCheck=readf ile("http.//www.somesite.co m/image.gif");
if($imgCheck) echo "<img border=0
src=\"http.//www.somesite.co m/image.gif\" width=\"550\" height=\"80\"
alt=\"banner\"> ";
-------------------------
$fp = @fopen("http.//www.somesite.co m/image.gif","r") ;
if ($fp) {
echo '<img border=0 src="http.//www.somesite.co m/image.gif" width="550"
height="80" alt="banner">';
} else { echo 'Resource not valid'; }
------------------------
Thanks ;o

Dunno if that's it, but in your code you have
HTTP.//
instead of
HTTP://

Haha, no it isn't, ;)
It was my fault because I typoed the http:// when writing the message
onto the newsgroup lol. Sorry for that. I wrote that because I wanted
to hide the URL.

Tsssk....


But: if it doesn't work, why surpress error-messages?
Turn off error-surpressing, put error_reporting (E_ALL) in your script, and
me thinks you'll find the answer.

Probably has something to do with allow_url_fopen .

readfile() won't work because it echoes the output to the user (unless you've
buffered it).

fopen() should work, though.

It would help if you told us what happens when you try.
