Parsing data from a string into an array for each match

I've had experience with PHP building simple websites and have only
scratched the surface of what it's capable of, so in a sense I'm a newbie.
However the problem I have is that I want to be able to read a file, store
it into a string, and be able to look for patterns in it to extract. I know
what the regex expression is for getting the data, but not familiar with how
to read the string and for each match, store it in an array. I haven't been
able to find any sample code and my php geek buddy is on vacation.

<?php

$string = implode(file("classes.txt"));
$string = ereg_replace ("/r|/n", "", $string);

// this is where I have no clue

?>

Regex expression going to be used - "[A-Z]{3,4} [0-9.]{4} [a-zA-Z.
\n\r]*\(([0-9]|Var.)\) [a-zA-Z;,. \n\r-]*"

Also, if you know how to be able to READ a PDF file in PHP let me know.
Cutting and pasting twenty 6.1MB PDFs will get annoying. I'm just trying to
make a script to save me time in the future.

// I didn't look at the regex, just simply copied it here
$regex = "[A-Z]{3,4} [0-9.]{4} [a-zA-Z.\n\r]*\(([0-9]|Var.)\) [a-zA-Z;,. \n\r-]*";


$num = preg_match_all("/$regex/", $string, $found_array);


if ($num === false) exit('Error in preg_match_all().');
echo '<pre>Found ', $num, ' matches: ';
print_r($Found_array);
echo '</pre>';

Check the fine manual for preg_match_all

There's some solution to create but few to actually read PDF.
Maybe you could find enough material in this two famous sites.
