Function Documentation

barcode_encode()

barcode_encode	(		$code,
			$encoding )

Encodes $code with $encoding using genbarcode OR built-in encoder if you don't have genbarcode only EAN-13/ISBN or UPC is possible.

You can use the following encodings (when you have genbarcode): ANY choose best-fit (default) EAN 8 or 13 EAN-Code UPC 12-digit EAN ISBN isbn numbers (still EAN-13) 39 code 39 128 code 128 (a,b,c: autoselection) 128C code 128 (compact form for digits) 128B code 128, full printable ascii I25 interleaved 2 of 5 (only digits) 128RAW Raw code 128 (by Leonid A. Broukhis) CBR Codabar (by Leonid A. Broukhis) MSI MSI (by Leonid A. Broukhis) PLS Plessey (by Leonid A. Broukhis)
