here is the meta_tags.txt

index.php|title 1|meta tags|meta description
aboutus.php|title 2|meta tags|meta description

and the get_meta.php is same what you provided. In index.php i placed the same here it is:

<?php include("get_meta.php"); ?>

Thing is the error is undefined variable errors..

This portion is not parsing:

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

something is wrong with the braces.. I don't know as I'm a newbie in php.
