Backlink

I’ve been using a PHP backlinking script from Laze.Net for a while now to show the referrers to my site. Unfortunately, the script hasn’t been updated to reflect changes in Yahoo’s new search string. So, I updated the string parsing code to correctly show the search terms. You can find the code below.

Warning: Adding recent referrs to your blog has some interesting consequences, which you may want to consider before making them publicly visible.

PHP:

$recentfile = "backlink.txt";

$mydomain = "freecapitalists.org";

$displaynum = 10;

$displaychar = 30;

$recent = file($recentfile);

$amount = count($recent);

if ($amount >= $displaynum) {

    $start = 1;

    $amount = $displaynum;

}

for ($x = ($amount-1); $x >= 0; $x--) {

    if (eregi("google.", $recent[$x]) || eregi("search.msn.", $recent[$x]) ||

            eregi("atomz.com", $recent[$x]) || eregi("lycos.", $recent[$x]) || eregi("yahoo.", $recent[$x]) ||

            eregi("altavista.", $recent[$x])) {

        if (eregi("google.yahoo", $recent[$x])  ) {  

            list($first, $rest) = split("p=", $recent[$x]);
