I’ll just assume you know of the php.net website. You know, your first reference to any PHP related problem/function/class/… ? But did you know there are a lot more PHP sites out there, that you might benefit from?
Redesign#
Did you know for instance, there’s a new design coming for the main site? The current layout is a 1999 version, that should soon get updated.
PHP site redesign
Talks & presentations
Granted, this contains mostly outdated presentations, but some are still very useful. You can find them all on talks.php.net . There are still useful talks there about the internals of PHP , debugging (mostly Xdebug), Security , …
Code testing & analysis#
On gcov.php.net you can spot the status of automatic code testing of current PHP code. Absolutely worthless for the average joe, but gives some nice insight into their inner workings. :-)
PECL#
This is a more familiar website (pecl.php.net ), where PHP Extensions are held that are not included in the main PHP code. Includes very useful extensions such as APC , memcache & Xdebug .
A Wiki#
Like any good coding site, there’s a wiki . It seems to be lacking a lot of info, but can be a good place for references.
