if you really *must* go the text route - which as Steve says is not
wise, why don't you read through this file once per day and make many
smaller files one per category, and also make them into php arrays.
This way you just have to include the file and output the array.
BCList2.txt -> many categoryfiles
category files->php array files
Guncel.php
<?php
$arrayURLs = array(
' /news/./401673.asp|Erdoðan: 301'i deðiþtirmeye varýz',
' /news/./401477.asp|'Türkiye'den komþularýna saldýrý olmaz'',
);
?>
......
since you only make the txt file once per day, then you must prepare
better your input, before you use it inside your php application.
I'm with Steve though - use MySql it's fast and easy to change.
