In a low-level language like C, that matters. One doesn't have strings, one has numbers that happen to map to a symbol. In PHP and other high-level languages, strings are their own datatype. They may or may not even be stored as standard ascii number codes in order internally. You have to think of them as strings, not as numbers. There are no numbers involved here. There are only strings. > Likewise "a" is DEC 97 (0110 0001) and "z" is DEC 122 (0111 1010) and if I > compare "a" to "z" , it will always be less by numeric definition. In C or C++, yes. In PHP, do not assume the same string->number mapping. Numeric definition is irrelevant. -- Larry Garfield AIM: LOLG42 larry@xxxxxxxxxxxxxxxx ICQ: 6817012 "If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it." -- Thomas Jefferson -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
