65. DATABASE CONNECTABLES
PHP Supports MOST database connections
MySQL, Oracle (OCI8), Postgres, Sybase
First, it connects to the database.
Second, it makes it’s SQL query in the flavor.

Err I mean: a result set of information returns.
72. MORE DB FUN
Take the resource, and use it.
<?php
while($bucketArray = mysql_fetch_array($bucket)):
echo “$bucketArray[‘skintype’];
endwhile;
73. MORE DB FUN

endwhile;
You could also make objects out of each row.
74. PHP PLATFORMS
Yes, I am in fact, a broken record.
Many out there in the world.
Zend - Granddaddy of them. Many server solutions
CakePHP - MCV implementation
CodeIgniter - Better.
And many many more
75. CODE IGNITER
WIN
Best documentation out of all
Easiest Model... err.. model
You don’t have to conform your
data model to their will.
Full MCV implementation.
PHP Best Practices!
