'Convert all characters to dec or hex HTML code equivalent

Is there a way I can convert ALL characters, including regular ones, using PHP to something like this:

&\#38; &\#233; &\#224; &\#231; &\#60;

When I say regular characters I mean to say chars like "ABCD123!@#$", etc.

Is this possible?

There are several ways. One is

join('', array_map(create_function('$c', 'return "&#".ord($c).";";'), str_split($string)));

Piggy-backing on Alex's/Anomie's answer, to get full Unicode support, you could use the package at http://hsivonen.iki.fi/php-utf8/ to do:

'&#' . join(';&#', utf8ToUnicode($str) . ';'
