Remote File Exists

[unkwntech]

I'm looking for a quick way to check if a remote file exists I have this now:

$url = 'http://money.cnn.com/data/commodities/index.html?cacheBust=' . rand('0', '99999999999');
if(!file_exists($url)){die("I couldn't get the crude price the page is no accessable.");}

But even though I know the page exists this does not work, the PHP manual hints that this is the wrong function for a remote file.

I suppose I should ask how to get the size of this file since:

$data = fread($fh, filesize($url));

 

doesn't work.

A simple function for return the length of a link, or a file.

<?php
function urlfilesize($url,$thereturn) {
if (substr($url,0,4)=='http') {
$x = array_change_key_case(get_headers($url, 1),CASE_LOWER);
$x = $x['content-length'];
            }
else { $x = @filesize($url); }
if (!$thereturn) { return $x ; }
elseif($thereturn == 'mb') { return round($x / (1024*1024),2) ; }
elseif($thereturn == 'kb') { return round($x / (1024),2) ; }
}

?>

The example :
<?php
echo urlfilesize('http://www.tayo.fr/remote-irc-tutoriel.php','mb')

?>

Did you want to get the filesize, or simply copy the contents of a remote file into a variable/local file?

Well I'm loading it into a variable and I need the size for fgets().

And I tryed that script and it returns 0.
