Hey WanWizard, if i've a text like this(mixture of text & codes as we use in CI forum generally)...

Code:

$text = 'Good morning.<code>echo 'PHP is a great language';</code> Today is a great day';

Then, can GeSHi will able to color codes which present inside "colorTag" & leave rest text as usual as CI forum do.

No, geshi is just a highlighter.

You have to create the proper CSS code for geshi to work with, then use some technique ( for example a preg_match() ) to get the code blocks from the text, run the code blocks through gehsi, and reinsert them into the text. Geshi output will contains lots of span's that uses CSS to highlight.

Check the docs on the Gehsi site, they explain everything.

Exactly in this situation(use some technique for example a preg_match() to get the code blocks) i've stuck. I've piece of code for this. But, it's not working properly. Here is that code...

Code:

$parentstring = preg_replace_callback( '#<code>(.*)</code>#', 'mycallback', $parentstring);

function mycallback($matches)
{
   // matches[0] contains the complete pattern: <code>...</code>,
   // matches[1] contains only the contents between the code tags
   // to make sure it goes ok, only highlight the stuff between.
   return '<code>' . highlight_code($matches[1]) . '</code>';
}

[eluser]WanWizard[/eluser]
what's not working properly? your highlight_code() function? The rendering of <code> tags?

[eluser]mi6crazyheart[/eluser]
Actually, it couldn't able to enter to the "mycallback()". May be, some problem with that REGXP...

Code:

#<code>(.*)</code>#

I use it to parse BBcode, I use

Code:

$rawmsg = preg_replace_callback('#\[code(=.*?)?\](.*?)([\r\n]*)\[/code\]#si', '_parse_bb_code', $rawmsg);
