Re: [PHP3] Sorting multiple arrays From: Andrew Chen (achen <email protected>)
Date: 01/04/99

I haven't looked at PHP in a little bit, so though the syntax will be
wrong, the ideas will be right. I think you can create associative arrays
(otherwise known as hashes) in PHP3 through:

$val = ("berlin"=>"bier",
        "amsterdam"=>"dope",
        "paris"=>"wine",
        "brussels"=>"food");

"berlin" would be the key, and "bier" is the value. The idea is that
you can get a value by using the key, for example:

$val{"berlin"} evaluates to "bier" -- the syntax is probably wrong, so
                                      make sure you check.

Anyway, if you look in the array section of the manual, there is a
specific function to do this... a quick glance yields usort() as a
candidate. I could be wrong-- check it out.
