You could also do this:
$fp = fopen($filename, "r");
while(!feof($fp)) {
$string = fgets($fp, 25); //25 specifies how many chars to read in
//process string here
}
fclose($fp);
The above code has not been tested, but it should give you an idea.
One thing I have noticed is that reading an entire file into PHP's memory
can make PHP use a /lot/ of memory. The above method reads it 25 chars at
a time. You could also just use fgets($fp) and it would read until the end
of the line (depending on what verison of PHP you are using). See
$mirror.php.net/fgets for more info.

Ginsberg's Theorem:
(1) You can't win.
(2) You can't break even.
(3) You can't even quit the game.
Freeman's Commentary on Ginsberg's theorem:
Every major philosophy that attempts to make life seem
meaningful is based on the negation of one part of Ginsberg's
Theorem. To wit:
(1) Capitalism is based on the assumption that you can win.
(2) Socialism is based on the assumption that you can break
even.
(3) Mysticism is based on the assumption that you can quit the
game.
