Rainbow Username

[Black Snow]

Hi,

Can anyone tell me why this won't work? It's for creating rainbow usernames but for some reason it doesn't work.

if( strpos( $user['musername'], 'rainbow: true;' ) !== false ) 
{ 
    $i = $b = 0; 
     
    $username = ''; 

    $colours = array('d31539', 'ff7e00', 'ffc20e', '90d125', '187acb', '6f3198', 'ab1d8e'); 

    while( $i < strlen( $user['username'] ) ) 
    { 
        if( $b > ( count( $colours ) - 1 ) ) $b = 0; 
         
        $username .= '<span style="color: #' . $colours[ $b ] . '">' . $user['username'][$i] . '</span>'; 
         
        ++$b; 
        ++$i; 
    } 
     
    $user['musername'] = '<strong>' . $username . '</strong>';

I also made the usergroup HTML markup to:

<strong style="color: #FFBC58; rainbow: true;">
