check if file exist on remote website without knowing extension - php

Question

I need to find a file name _template on more than one remote server.
The file will have one of two extensions:
_template.htm
or
_template.php
I can find a file using cURL on a remote server which is easy but cant wrap my head around how to find one or the other.
The code is in a loop and it will search on about 20 different sites for this file, if it finds it just needs to say: Found it if it doesn't find any of the two files it needs to say: None Found.
Doing cURL twice takes too long to load.
Searching through the ftp array also takes too long.
My current code below that doesnt work, in know why it doesnt work thanks guys i would like to know how i can make it work: (This is in a loop)
$template_file = glob("/_template.{htm,php}", GLOB_BRACE);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $client_link.$template_file);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_MAXREDIRS, 10);
$data = curl_exec($ch);
curl_close($ch);
preg_match_all("/HTTP\/1\.[1|0]\s(\d{3})/",$data,$matches);
$code = end($matches[1]);
if(!$data)
{
echo "No Files Found<br>";
}
else
{
if($code == 200)
{
$filefound = 'Found'.$template_file;
}
elseif($code == 404)
{
$filefound = '404 File not Found';
}
}

The problem is with the glob function - that function matches paths on the local filesystem. Add a print_r($template_file);' after theglob` and you'll see that it doesn't match anything (or it only matches things on your local system).
What you need to do is build the URLs one-by-one:
foreach(array("htm", "php") as $ext)
{
// build the URL string
$url = "http://example.com/_template." . $ext;
// now do whatever you need to with the URL...
}
