file_exists problem

[blufish]

on the part of this code where it checks if file exists (which it does) it doesn't do what it's supposed to.

<?php
function showgarfield()
{
$month = $_GET['month'];
$year = $_GET['year'];
$syear = substr($year,-2);
echo 'http://images.ucomics.com/comics/ga/'.$year.'/ga'.$syear.$month.'31.gif';
if (file_exists('http://images.ucomics.com/comics/ga/'.$year.'/ga'.$syear.$month.'31.gif'))
{
echo 'http://images.ucomics.com/comics/ga/'.$year.'/ga'.$syear.$month.'31.gif';
}
}
showgarfield();
?>

what is the output for "echo 'http://images.ucomics.com/comics/ga/'.$year.'/ga'.$syear.$month.'31.gif';" ?

 

have you tried put this output to a browser address bar to see what happens ?

Yes, I have and it does it right and the file does exist.

<?php
$month = $_GET['month'];
$year = $_GET['year'];
$syear = substr($year,-2);
echo 'http://images.ucomics.com/comics/ga/'.$year.'/ga'.$syear.$month.'31.gif';
if (file_exists('http://images.ucomics.com/comics/ga/'.$year.'/ga'.$syear.$month.'31.gif'))
{
echo 'http://images.ucomics.com/comics/ga/'.$year.'/ga'.$syear.$month.'31.gif';
}
?>

I changed the code, it still doesn't work...

[asmith]

if there's no problem, Can you give me the full url of this image?

it's a garfield comic, it's just that the part where it check if the file exists doesn't work, the code is supposed to display garfield comics.

[asmith]

change it to this to see what's the problem :

 

<?php
$month = $_GET['month'];
$year = $_GET['year'];
$syear = substr($year,-2);
echo 'http://images.ucomics.com/comics/ga/'.$year.'/ga'.$syear.$month.'31.gif';

$url = 'http://images.ucomics.com/comics/ga/'.$year.'/ga'.$syear.$month.'31.gif';
if (file_exists($url))
{
echo 'http://images.ucomics.com/comics/ga/'.$year.'/ga'.$syear.$month.'31.gif';
}
else
{
echo "this $url cant be found";
}
?>

http://images.ucomics.com/comics/ga/2008/ga080731.gifthis http://images.ucomics.com/comics/ga/2008/ga080731.gif cant be found

 

Does it matter that this website isn't my website?

[asmith]

Yea, true.

 

I tested it on my own, and it can't find it there too.

 

check http://ir.php.net/manual/en/function.file-exists.php for similar functions.

I think so. Because PHP is a server side language and it knows nothing other than the server it is installed. So, I guess you cannot check whether any file exists in other PC using PHP.
