Questions for the pros

[apw]

Hello

 

I had 2 questions that maybe someone can help me with.

 

My first question is about restricting certin names when someone registers

on my website such as admin or guest.  However I may get the occasional

person who may try names such as admin2 or guest2.  How do I setup some

sort of restriction that not only blocks names such as admin or guest but also

any other names that may have the word admin or guest in the name?

 

My second question is about adding commas in numbers over 999.  My script

looks very funny with numbers over 999 that have no comma in them.  How

would you do this?

 

Thanks

1. if (preg_match("/.*(admin|guest).*/", $username)) { /* do something */ }

2. $formatted_number = number_format(123456.789, 2); // outputs 123,456.79
