You can also try this HTML DOM parser: http://simplehtmldom.sourceforge.net/

An option:

<?php

$database = 'meta_tags.txt';
$meta_db = fopen($database, 'r');

$page = $_SERVER['SCRIPT_NAME'];
$page = substr($page, 1);

while($data = fgetcsv($meta_db, 9000, '|'))
{
    if($data[0] == $page)
    {
                $title = $data[1];
        $meta_keywords = $data[2];
        $meta_description = $data[3];
    }
}

?>
