hi all,

as my title says, i'm facing a problem with preg_replace. The thing i'm working on is a simple phpbb mod (really simple): i want to change the color and the weight of certain words.
here's the sample i'm entering in the post field:

class hello
Hello extends Hi
public abstract class Hello
public abstract class Hello extends Hi
public interface Hello

the output i want to get is this:

class hello
Hello extends Hi
public abstract class Hello
public abstract class Hello extends Hi
public interface Hello

this is the code i'm using to do so:

PHP Code:

    $patterns = array();
    $patterns[] = '(public\s)?(abstract\s)?(class|interface)?\s([A-Z][a-zA-Z0-9_]+)';
    $patterns[] = $patterns[0].'\sextends\s([A-Z][a-zA-Z0-9_]+)';

    $replaces = array();
    $replaces[] = "[color=green:$uid][i:$uid]$1$2$3[/i:$uid][/color:$uid] [color=darkblue:$uid][b:$uid]$4[/b:$uid][/color:$uid]";
    $replaces[] = $replaces[0]." [color=green:$uid][i:$uid]extends[/i:$uid][/color:$uid] [color=darkblue:$uid][b:$uid]$6[/b:$uid][/color:$uid]";
    for($i=0; $i<sizeof($patterns); $i++)
        $text = preg_replace('#'.$patterns[$i].'#', $replaces[$i], $text); 

don't mind the $uid, it is set, and works fine. Now, my problem is that it all works except for the "extends" word: it just don't change to green, italic. My output looks like this:

class hello
Hello extends Hi
public abstract class Hello
public abstract class Hello extends Hi
public interface Hello

when i display the $text var during the for loop, together with the $replace[$i] var, it says that "extends" is placed before the change of color code, like this:

Code:

extends[.color=green][.i][/i][/color]

anyone knows how to fix this?

thanx in advance,
UnrealEd

I am tired (2:00 AM for me), but what is with the:

PHP Code:

$patterns[] = $patterns[0].'\sextends\s([A-Z][a-zA-Z0-9_]+)'; 

Why do you have "$patterns[0] ." there? I am not seeing *why* that should be there. Similar problem in the $replaces[].

forget about it, i've solved it 5 days ago
the reason why it didn't work is because the $pattern[0] also matches the first part of $patterns[1], therefore it will replace the match, and $patterns[1] will return false
