how large? for very big files it's dangerous to read them in all at once,
as was exampled in other replies. I would say that large in this case would
be anything bigger than 5 Mb (this is a very rough estimate, we could have
a whole thread devoted to this [issue])

your uisng php5 I hope? if so (error checking code left as an
exercise to the reader):
<?php
foreach (array_filter(explode("\n", file_get_contents($myFile))) as $line) {
echo substr($theDataLine[$i], 0, 5), " - ",
substr($theDataLine[$i], 7, 46),"\n";
}
?>
