Housie Tickets Generator in PHP

This PHP script generates housie tickets using Emojis instead of numbers. Each ticket has 3 rows with 9 columns of which 4 are blanks and the rest have unique but random emoji emoticons.

The emojis are rendered using 160×160 images extracted from the Apple Emoji font and would therefore render on any browser and device.
