Running PHP4 and PHP5 on the same box.


As the sole systems administrator for the Linux box hosting the University’s website, I was asked nicely by the lead web developer, last to last week, to set up php5 alongside the existing php4 installation. A new component of the website uses php5, and rolling out that component was on top of the list.

I used Tim Dorr’s simple article, “PHP4 and PHP5 Side-By-Side“, to get php5 up and running on the system.

    well, btw php5 is working pretty smoooothly and that too without messing with the php4 installation. Although we agreed on using a different extension for files that were supposed to be parsed by php5 engine (extension = .php5)… but the Good ol’ apache and it’s .htaccess support comes in very handy in over-riding our assumptions.

    The situation is now.. *.php files are parsed with PHP4 for the entire site, excluding the new system that was added — where all *.php files are parsed using the newly added Php5 engine. Same extension, but two different parsers — thanks to .htaccess!

    It’s worthwhile to note that PHP5 has a much reliable and better OOP support~! PHP4 is preferred, where there is not a strict requirement for OOP.
