Quick and easy way to have multiple configurations for things like charts.

charts.php

<?php
	$charts = array(
		'live1-ajax-total-count' => array(
			'type' => 'line',
			'title' => 'LIVE1 Total Count (ajax)',
			'sql' => 'select .... ',
			'callback' => 'minute_counts',
		),
		'live2-ajax-total-count' => array(
			'type' => 'line',
			'title' => 'LIVE2 Total Count (ajax)',
			'sql' => 'select .... ',
			'callback' => 'minute_counts',
		),
	);

function get_chart($chart_id) {


	if (!empty($charts[$chart_id])) {
		$data = mysql_query($charts[$chart_id]['sql']);
		$data = call_user_func($charts[$chart_id]['callback'], $data);
		return $data;
	}

}

function get_charts() {
	return array_keys($charts);
}

function minute_counts($data) {
	// Data expectation:
	// array('minute' => count);
	// return json array
}
?>
