Put together from various tutorials and forum posts, etc...

First piece of PHP I have ever written (I'm using tons of deprecated methods and am probably wrecking a dozen of conventions).

If you have tips to improve it -> shoot ^^

<?

    $user = "all";

Bookmarked for the future!

Yea, using pdo woulda been better, but it works ;)

Please don't use this example if you're going to be doing anything remotely with sensitive data like storing ip's, usernames and such. Also this uses a outdated and non-standard php library now as the new standard is mysqli which was introduced a few years ago (think this as a pre 2012 script).

 

If you want a good correct example use these instead;

Has all the code you need to know. It's also explained on this guys site; http://goddfree.com/rsbot-script-stats/

Here's a better example:

<?php

$username = "";
$password = "";
$database = "";
$host = "";

$sql = new SQLe($host, $username, $password, $database);

if (isset($_GET['script']))
{
	$name = (isset($_GET['user']) ? $_GET['user'] : "all";
	
	$q = $sql -> select($_GET['script'], array("username" => $name));
	if ($sql -> num_rows($q) == 1)
	{
		$row = $sql -> fetch($q);
		//Call data like $row['value']
		//Image stuff here
	}
}

?>

SQLe class:

<?php

define("SQLE_DATETIME_NOW", 40966);
define("SQLE_NULL", 400968);
