A simple solution to your first question could go a little something like
this:

<?php
$txtfile = file('text.txt' );
$txtfile = implode('\n',$t xtfile);
?>

Then run some sort of search function on $txtfile, such as strstr() or
preg_match().

The answer to your second question is a little more complicated because it
would probably involve a regexp. Suppose you wanted to create a line that
contained the words "A NEW LINE" before the special word...

<?php
$txtfile = <<<BLOCK
foo bar baz something something more
something else SPECIALWORD
BLOCK;

$txtfile = preg_replace( "/(\n.*)(SPECIALW ORD)/", "\nA NEW LINE$1$2",
$txtfile );
?>
