I've learned the beautiful method of managing PHP scripts using the safe method of using $_POST and $_GET to process data rather than using simple variables. Being in an array, I can write a global function that will globally clean all my variables as opposed to having to do it one by one:

$_POST = cleanInput($_POST);

The same with outputting data:

$q = safesql("SELECT * FROM table");
$r = mysql_fetch_assoc($q);
$r = cleanInput($r);

WOW! Man, this new script is so tight (I hate verbose code)... I'm really happy with the way this project's going on so far. I've also been dabbling a bit in Javascript, since I think it's incredibly crucial to making stuff idiotproof.

But honestly, the more I work with PHP, the more I see it simply as a templating engine. It's not a real language. It doesn't really do anything awesome... bah.
