Versions of Apache2 and PHP5 are already installed on current shipping Macs, however Apache 1.3.33 and PHP 4.x are enabled by default. Adjusting your configuration to use the newer versions isn't too complex although it does require editing config files.
Or, you could install newer versions of Apache2 and PHP5 using one of the easy installers which are available:
PHP 5 [entropy.ch] from Marc Liyanage
Apache2 [serverlogistics.com] from Server Logistics
MySQL has an easy installer [serverlogistics.com] from Server Logistics or you can install source using the instructions from Apple [developer.apple.com].
