hi

i have a code like this (selected from a Database, so is different as this, as it is posted by users)
[code]
<?
echo 'this is php higlighted';
?>

<html>
this is as html highlighted
</html>

script language="text/javascript" (with < and > but coz that posting problem)
// this is javascript highlighted
/script (with < and > but coz that posting problem)

<style>
/*
this is css highlighted
*/
</style>
[/code]

now i got for each highlighter it's own function called: highlight_php, highlight_html, highlight_js and highlight_css and next to that i got a function called 'highlight($input, $unparse = false)'

now i use this to highlight html
[code]
preg_match_all('#(<.*?>)#is', $highlighted, $matches);
for ($i = 0; $i <= count($matches[0]); $i++)
{
$replacer = highlight_html($matches[0][$i]);
$highlighted = str_replace($matches[0][$i], $replacer, $highlighted);
}
[/code]

this is the function highlight_html():
[code]
function highlight_html($input)
{
/**
* These three array will make it easyer to preg_replace to colors
*/
$commands_boldblue = array

return $temp;
}
[/code]

but when i call this function it also indexes php, script and style. and as far as i know it is this 'preg_match_all('#(<.*?>)#is', $highlighted, $matches);'
so does anyone know how to index only html, and ignoring php, script, and style??

greetzz

oh btw, i encoded some things coz otherwise it wouldn't work proper. you'll see what they're in the array

this is not realy regex, but in the function highlight_html() i put in the following before i change anything:
[code]
<?php
if(strstr('style', $input) OR strstr('<?', $input) OR strstr('<?php', $input) OR strstr('script', $input))
{
    return $input;
}
?>
[/code]

(stupid i didn't came on that earlier :P)
