OK I have added bbcode to a script and everthing works fine but now what I need to do is add
tags to format code. I can format the text between the code tags anyway I want but what I'm having trouble doing is stoping bb tags outside the code tags from formating the text inside the code tags.
Example:
on this forum if I type {b} in brackets here >>
[b] this is bold text
[code=php]then text inside the PHP tags is not bold but the bold text continues after the ending PHP tag text is still bold after the PHP tags
[/b]{/b}
I would really appreciate any help getting this to work!!
Here is the bbcode function I'm using ([ code] tages are not included because I don't know where to start).
Please ignore the spaces in the patterns array because this forum formats the bbtags inside the PHP tags.
function bbcode($string){
$patterns = array(
'`\[ b\](.+?)\[/b\]`is',
'`\[ i\](.+?)\ /i\]`is',
'`\[ u\](.+?)\[/ u\]`is',
'`\[ strike\](.+?)\[/ strike\]`is',
'`\[ color=#([0-9A-Fa-f]{6})\](.+?)\[/color\]`is',
'`\[ email\](.+?)\[/email\]`is',
'`\[ img\](.+?)\[/img\]`is',
'`\[ url=([a-z0-9]+://)([\w\-]+\.([\w\-]+\.)*[\w]+(:[0-9]+)?(/[^ \"\n\r\t<]*?)?)\](.*?)\[/url\]`si',
'`\[ url\]([a-z0-9]+?://){1}([\w\-]+\.([\w\-]+\.)*[\w]+(:[0-9]+)?(/[^ \"\n\r\t<]*)?)\[/url\]`si',
'`\[ url\]((www|ftp)\.([\w\-]+\.)*[\w]+(:[0-9]+)?(/[^ \"\n\r\t<]*?)?)\[/url\]`si',
'`\[ flash=([0-9]+),([0-9]+)\](.+?)\[/flash\]`is',
'`\[ quote\](.+?)\[/quote\]`is',
'`\[ indent](.+?)\[/indent\]`is',
'`\[ size=([1-6]+)\](.+?)\[/size\]`is'
);
$replaces = array(
'<strong>\\1</strong>',
'<em>\\1</em>',
'<span style="border-bottom: 1px dotted">\\1</span>',

'<span style="color:#\1;">\2</span>',
