PHP / SQL Diagrams

[johnoc]

hey guys,

any sites where there is diagrams of overviews..architectures..compenents etc of PHP and SQL any of that kinda thing??

its for a background and history to PHP/SQL

I believe the PHP Manual has a few such diagrams.
Look at the Zend API section, for example.

For SQL, you might look in the direction of database normalisation, perhaps papers by Codd.
PHP Builder does have an article, but the diagrams are just tables used for elaboration.
