There are virtually no changes in PHP5 that break existing PHP4 code.

Some things like register_globals and auto-escaping of incoming variables 
are turned off by default in PHP5 (they were on by default in PHP 4.0 
IIRC) but can be switched on in php.ini or a .htaccess file in a matter of 

PHP6 will be a more painful switch for those with legacy code. (But still 
fairly painless for those updating from PHP5-style code.)
