You could do:
$some_array = file("your_file.txt");

and then search the array for a line that starts with those characters.

I would say to use the method described above.

Try writing it out like this.
Load file into an array
For each line in the array
Search the line for the string
If the string exists, set $var = line and exit
Else do error stuff

Try this:
<?php
$text = <<<HERE
Sample 
text.
HERE;

$string = str_replace('\n', '', $text);

$other_string = str_replace("\n",'', $text);

echo "<pre>".$string."\n\n".$other_string."</pre>";
?>

What happens, and why?
