PHP backlink checker script

Bookmark on del.icio.us

This is probably the simplest script that anyone knowing (or even learning) PHP can create in about 15seconds. But I will still post it here just in case anyone is a total noob at PHP.

Purpose of this script: To check a certain given backlink on hundreds of webpages provided you know the URL of every webpage.

<?php

$source = file_get_contents("source.txt");
$needle = "www.IamtryingtocheckThisPage";   //without http as I have imploded the http later in the script
$new = explode("\n",$source);

foreach ($new as $check) {
$a = file_get_contents("http://".trim($check));

if (strpos($a,$needle)) {
$found[] = $check;
	 } else {
	 $notfound[] = $check;
			}
						}

echo "Matches that were found: \n ".implode("\n",$found)."\n";
echo "Matches that were not found \n". implode("\n",$notfound);
?>


or Other way
<?php
function check_back_link($remote_url, $your_link) {
    $match_pattern = preg_quote(rtrim($your_link, "/"), "/");
    $found = false;
    if ($handle = @fopen($remote_url, "r")) {
        while (!feof($handle)) {
            $part = fread($handle, 1024);
            if (preg_match("/<a(.*)href=[\"']".$match_pattern.
"(\/?)[\"'](.*)>(.*)<\/a>/", $part)) {
                $found = true;
                break;
            }
        }
        fclose($handle);
    }
    return $found;
}
// example:
//if (check_back_link("http://www.abc.com", "http://www.xyz.com")) echo "link exists";
?>
