BB-code regex help needed!

(1/2) > >>

Curbow 5:
I use the following coding for [ size ] and [ color ] bb-code:


--- Code: ---$message = eregi_replace("\\[size=([^\\[]*)\\]([^\\[]*)\\[/size\\]","<span style=\"font-size: \\1px;\">\\2</span>",$message);   
$message = eregi_replace("\\[color=([^\\[]*)\\]([^\\[]*)\\[/color\\]","<font color=\"\\1\">\\2</font>",$message);

--- End code ---

When I input the following bb-codes, only the first one really works, the second one only works for the [ color ] and the other two don't do anything:


--- Code: ---[color=red][size=18]test[/size][/color]
[size=18][color=red]test[/color][/size]
[size=18][color=red]test[/size][/color]
[color=red][size=18]test[/color][/size]

--- End code ---

I don't really understand what the problem is... If anyone is willing to take a look at the coding and tell what I did wrong, I'd be really gratefull!  :D

Shadow:
Just wondering, why don't you just use the <font> tag for the size? :-/

Curbow 5:
i'm not quite sure.... but would it make a difference?

Chris Cromer:
Less html... but other than that no.

Spaceman-Spiff:
ereg and eregi are much slower than preg
if you can, you should use preg_replace instead
