Is there any reason why either ereg or preg would be more desirable over the other?

Ereg uses POSIX regular expressions which only work on textual data and include locale functionalily. preg uses PCRE, which work on binary as well as textual data and is a more sophisticated regex engine, incorporating minimal matching, backreferences, inline options, lookahead/lookbehind assertions, conditional expressions and so on. They are often faster than the POSIX equivalents also. -- http://www.web-buddha.co.uk http://www.projectkarma.co.uk
