when given a valid timestamp it creates a png image with the given date format and png background template in the designated folder. To optimize the process and avoid having to create pngs every time the site loads it caches created pngs and use them if a given date png already exists.

get font ttf path
$font = $_SERVER["DOCUMENT_ROOT"].'/Arial.ttf';

png file template that's used as the background
$png_path = $_SERVER["DOCUMENT_ROOT"].'/date.png';

create a DatePNG object with the current timestamp and png file template
$datePNG = new DatePNG($time(), $png_path);

define the folder which the font files should be created (this folder must exist and writable)
$datePNG->folder = $_SERVER["DOCUMENT_ROOT"].'/dates';

define the text style and date pattern, each text pattern in each associated array

Possible values for the associated array with keys
$datePNG->formats = array(
	array('format'=>'d','font'=> $font, 'size'=>14,'angle'=>0,'x'=>5,'y'=>20,'color'=>'0x666666', 'linespacing' => 1.5),
	array('format'=>'M','font'=> $font, 'size'=>8,'angle'=>0,'x'=>5,'y'=>37,'color'=>'0x666666', 'upper_case' => true)

create the png and return the path of the created date png
$date_path = $datePNG->create_png();

echo '<img src="'.$date_path.'" alt="date" />' ;
