My function as it stands aims to upgrade all the normal highlight_string() tags and bring them into the 21st century with valid XHTML 1.0 strict codes.

Using a function I tried to buid using 2 other functions I have run into a problem trying to integrate them together;

http://us3.php.net/manual/en/function.highlight-string.php

PHP

<?php
function bbcode($s)
{
   $s = str_replace("]\n", "]", $s);
   $match = array('#\[php\](.*?)\[\/php\]#se');
   $replace = array("'<div>'.highlight_string(stripslashes('$1'), true).'</div>'");
   return preg_replace($match, $replace, $s);
}
?>

And

PHP

<?php
function xhtml_highlight($str) {
   $str = highlight_string($str, true);
   $str = str_replace(array('<font ', '</font>'), array('<span ', '</span>'), $str);
   return preg_replace('#style="color:(.*?)"#', 'style="color: \\1"', $str);
}
?>

My function at the moment is;

PHP

function xhtml($str) {
   $str = highlight_string($str, true);
   // $str = substr($str, 29, -15);
   $str = str_replace(array('<font ', '</font>','<code>','</code>'), array('<span ', '</span>','<div class="php-code">','</div>'), $str);
   return preg_replace('#style="color:(.*?)"#', 'style="color: \\1"', $str);
}

Which is just highlighting the entire content, I want to only highlight the code between the [ php ] tags, everything I try to do this doesn't work so I was wondering if someone could help me a lil'.

Cheers

way to steal my example functions and not be able to modify them, mate ^_~

PHP

<?
function xhtml_highlight($str) {
   $str = highlight_string($str, true);
   $str = str_replace(array('<font ', '</font>','<code>','</code'), array('<span ', '</span>','<div class="php-code">','</div>' ), $str);
   return preg_replace('#style="color:(.*?)"#', 'style="color: \\1"', $str);
}
?>

PHP

<?
function bbcode($s)
{
   $s = str_replace("]\n", "]", $s);
   $match = array('#\[php\](.*?)\[\/php\]#se');
   $replace = xhtml_highlight('\\1');
   return preg_replace($match, $replace, $s);
}
?>

I didn't steal your functions

Both examples that I tried to combine were from;
http://us3.php.net/manual/en/function.highlight-string.php

I got it working in the end with some extra bb tags added on.

PHP

<?php
function bbcode($string)
{
   $string = preg_replace('~\[i\](.*?)\[\/i\]~is', '<i>\\1</i>', $string);
   $string = preg_replace('~\[b\](.*?)\[\/b\]~is', '<strong>\\1</strong>', $string);
   $string = preg_replace('~\[u\](.*?)\[\/u\]~is', '<u>\\1</u>', $string);
   $string = str_replace("]\n", "]", $string);
   $match = array('#\[php\](.*?)\[\/php\]#se');
   $replace = array("'<div class=\"php-code\">'.highlight_string(stripslashes('$1'), true).'</div>'");
   $string = preg_replace($match, $replace, $string);
   $font = array('<font ', '</font>','<code>','</code>');
   $span = array('<span ', '</span>','','');
   $string = str_replace($font, $span, $string);
   $string = preg_replace('#style="color:(.*?)"#', 'style="color: \\1"', $string);
   return $string;
}
?>

... but as usual, one problem goes and another one arises

Cheers for the help though Will ... should have posted back saying I'd solved it really

I was just teasing you mate...remember the discussion we had like..a month ago..about xhtml compliant string highlighting?I showed you an almost duplicate function that I was using. You know I'd never 'seriously' accuse you of stealing code...if I showed you it..your welcome to use it. XD

Glad you got it fixed tho.

Theres JavaScript to insert the tags yes, but to parse and change them into HTML code it uses a server side language

Javascript can't parse the tags...they need to be parsed on the server -- and sent to the browser as their proper html counterparts. Javascript is commonly used, as in the posting page for this forum...to trigger buttons which insert the code.
