]]> In web applications like an online-ticketing system, encoding the purchase reference number as barcodes on the ticket print or voucher can be quite useful in helping over-the-counter staff to quickly handle processes such as guest check-in using a barcode scanner.

There are many kinds of barcode formats out there to cater the types or amount of data you are trying to encode. However if you are just starting out for a bit of familiarization, generating 1D barcodes with PHP couldn’t be simpler with the free (for non-commercial use) PHP Barcode Generator class.

Extract the ZIP and use the following line to generate a barcode in a Code 39 barcode format encoding the string A1B2C3D3.

<div>
   <img src="html/image.php?code=code39&amp;o=1&amp;dpi=72&amp;t=80&amp;r=1&amp;rot=0&amp;text=A1B2C3D3&amp;f1=Arial.ttf&amp;f2=10&amp;a1=&amp;a2=&amp;a3=" alt="Barcode" />
</div>
