Read lines starting with in PHP

[vidyashankara]

[code]
TITLE PHP TEXT
HEADER PHP HEADER
!@##@
123!@#
$#%@#$
sdFSDAF
SDFSDF
[/code]

Lets say we have the above text file, how i select lines starting with TITLE or HEADER? I have the following code currently

[code]
$contents = file_get_contents(file.txt);
$title=  preg_replace('/^(?!TITLE).*?(?:\n|$)/m','',$contents);
[/code]

This does the job, But the script turns up a blank screen now and then because i have 5 of such lines in the script. The preg_replace command is the problem because the script runs really fast when i comment it out. Is there any better way to select lines starting with certain words?

This might be the long way around it, but it works...
[code]<?php
$file = file("file.txt");
foreach($file as $line)
    if(strpos($line,"TITLE") === 0)
        echo "<p>$line</p>";
?>[/code]
