PHP Code colouring

[missing-score]

Right, I hope I am posting this in the right place. I assume I am cos I think I will need PHP RegEx.

As on this board you get PHP code colouring. Is there a way that this could be done? Im not that good with regEx.

Any help appreciated.

PHP has a built in function for this.

Have a look here (http://www.php.net/manual/en/function.highlight-string.php).

Thanks.

Thanks for the link! That was alot easier than I was expecting! :D

Right, that works. Now, (this is why I thought RegExp) how do I make all text inside a [php] tag coloured in that way?

http://www.php.net/manual/en/function.ereg.php would be the function you using.

Could go something like this:


if (ereg('[php](.*)[/ php]',$string))
{
highlight your code
}


*Note, there is a gap between the / and php, that's just cause the format came out messed up if they were linked up together.

Sorry, that doesnt seem to work.

First, don't use the ereg functions, use the preg ones. 2nd, [ and ] should be escaped in a pattern, otherwise they dfine a character set

$someString = preg_replace( "/\\[php](.*)\\[/ php]/i", highlight_string( "$1" ), $someString );That should work

Note: remove the space in [/ php]

What is the variable 1, is that defined in the (.*) bit?

PS: I knew the [] should be unescaped, so I tried that too.


Thanks beetle, Ill give it a go.

$1 is not a variable per se, but a backreference to the 1st matched parenthical in the pattern. So, everything matched by (.*) is retrieved in the replace argument with "$1"

[missing-score]

Sorry, still no luck.

Here is my code



$_POST['code'] = preg_replace( "/\[php\](.*)\[\/ php\]/i", highlight_string( "$1" ), $_POST['code'] );

I have \\ behind all the [,], and /, But vB strips them out.

[beetle]

Can you write to a superglobal array like that? I'm not sure, but I think those are read-only. Use another variable to store the result

Ok, I'll have another go thanks.
