$t_post = nl2br(preg_replace (array_keys($bbcode), array_values($bbcode), $row["post"]));
echo $t_post;
?>
[/code]

Evrything works fine but theres 1 problem...
if the post is somethig like
[colour=blue]my name[/colour] its shows [blue]"my name"[/blue] in the colour chosen
but if its spread over multiple lines like
[colour=blue]
my name
[/colour]
it just spits out the same thing back

sorry if im confusing but the problem is it only works if the tags are on 1 line if they are spread over multiple lines it just spits back out the same thing

if anyone gets what im trying to say is there any way I can get around the problem

You need to add 's' to the end of each line. I couldn't find anything to explain what it exactly means in that usage, however "\s" is used to represent any whitespace character.

Also, you will probably want to add an "i" as well to make the replacements case insesitive so [ b ] == [ B ]

So the first line would be changed as follows:
[code]
"'\[B\](.*?)\[/B\]'" => "<b>\\1</b>",    --OLD LINE
"'\[B\](.*?)\[/B\]'is" => "<b>\\1</b>",  --NEW LINE
[/code]
