Explode $code by \n

[doa24uk]

Hi guys,

I've been wondering....

Is it possible to take the $code variable (used to store the text between the [CODE*] tags) and explode it by \n (newline) characters

for example

First Line
Second Line
Third Line

PHP Code:

<?php
$codelines = explode("\n", $code); // or \r\n if it uses this instead
echo "First line = $codelines[0]<br>";
echo "Second line = $codelines[1]<br>";
echo "Third line = $codelines[2]<br>";
?>

If so, where would I put it to be useful on the showthread page??
