PHP Backlink Checker
This function is usefull for peoples with a link directory where the links are stored inside a (MySQL) database. The PHP script is easy to use to find out if a reciprocal link still exists on the corresponding webpage. It takes care about the trailing slash in urls and can be used with (almost) every url. Inside the function is a check against a regular expression pattern and the result is a simple boolean.
CODE from: http://www.finalwebsites.com
<?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 $found;
}
// example:
//if (check_back_link(“http://www.web-tool.ws”, “http://www.fixwordpress.net”)) echo “link exists”;
?>
function check_back_link($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.web-tool.ws”, “http://www.fixwordpress.net”)) echo “link exists”;

One of the most important factors in Search Engine Optimization is the number of incoming links to your website, the relevance of the website linking to you, the anchor text used for the link, and the page ranking of the webpage linking to you. We have tried it and have found it very useful to increase our page rank on google. We are a tender information portal, http://www.tradereader.com. We used tenders as our anchor text. We suggest any site to try and increase the backlinks.
