• Barcode-Images using libgd (png, jpg,gif),
• HTML-Images (using 1×1 pixel and html-table)
• silly Text-Barcodes

PHP-Barcode encodes using

• a built-in EAN-13/ISBN Encoder
• genbarcode (by Folke Ashberg), a command line barcode-encoder which uses GNU-Barcode genbarcode can encode EAN-13, EAN-8, UPC, ISBN, 39, 128(a,b,c), I25, 128RAW, CBR, MSI, PLS genbarcode is available at www.ashberg.de/php-barcode

WHAT YOU NEED TO BE ABLE TO USE PHP-BARCODE

• You need php>4 on your system.
• You need the gd2-extension to be able to render images.
• You need a TrueTypeFont if you want to see the CODE below the bars.
• You need genbarcode (from www.ashberg.de/php-barcode) in you want to use another encoding than EAN-12/EAN-12/ISBN

Copy the following files into your html/php-directory

• php-barcode.php — main library
• encode_bars.php — built-in encoders optional:
• barcode.php — Sample-File
• white.png — for HTML-Images
• black.png — for HTML-Images

 UNIX: A TrueTypeFont isn't included in this distribution! Copy one into the html/php-directory and change in php-barcode.php $font_loc (change the arialbd.tff to your font name). arialbd.ttf from Windows looks great. WINDOWS: If you use Windows the font should be located automatically. 

 If you want to generate not only EAN-12/EAN-13/ISBN-Codes you have to install genbarcode, a small unix-commandline tool which uses GNU-Barcode. genbarcode is available http://www.ashberg.de/php-barcode , read genbarcodes README for installation. If you have installed genbarcode not to /usr/bin set the $genbarcode_loc in php-barcode.php . 

 If everything works fine you should see an image if you call http://localhost/path/barcode.php Or call http://localhost/path/barcode.php?code=&encoding=&mode=&size=

If you need more then the sample barcode.php can do, you need to build your own.

function barcode_encode(code, encoding) encodes $code with $encoding using genbarcode OR built-in encoder if you don’t have genbarcode only EAN-13/ISBN is possible

You can use the following encodings (when you have genbarcode):

ANY	choose best-fit (default)
EAN	8 or 13 EAN-Code
Pipe	$1
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)

• array[encoding] : the encoding which has been used
• array[bars] : the bars
• array[text] : text-positioning info

function barcode_outimage(text, bars [, scale [, mode [, total_y [, space ]]]] )

Outputs an image using libgd

text	the text-line (:: . )
bars	where to place the bars (. )
scale	scale factor ( 1 < scale < unlimited (scale 50 will produce 5400x300 pixels when using EAN-13. ))
mode	png,gif,jpg, depending on libgd ! (default=’png’)
total_y	the total height of the image ( default: scale * 60 )
space	space

default:
$space[top] = 2 * $scale;
$space[bottom]= 2 * $scale;
$space[left] = 2 * $scale;
$space[right] = 2 * $scale;

function barcode_outhtml(text, bars [, scale [, total_y [, space ]]] )

returns(!) HTML-Code for barcode-image using html-code (using a table and with black.png and white.png)

text

bars

scale

total_y

space

default:
$space[top] = 2 * $scale;
$space[bottom]= 2 * $scale;
$space[left] = 2 * $scale;
$space[right] = 2 * $scale;

function barcode_outtext(code, bars)

Returns (!) a barcode as plain-text

ATTENTION: this is very silly!

text	the text-line (:: . )
bars	where to place the bars (. )

README.md

This is a re-working of php-barcode by Folke Ashberg. Currently, my version only creates EAN-13 barcodes, however I plan to make the source modular to allow for additions of ISBN, Code 12, and others.

Folke did a lot of good work, but it is nigh unreadable, I think, and I wanted to fix that. Because of this, too, it is really hard to add newer barcode types.

I also needed an on-the-fly barcode solution for a freelance job. This code has been in production for several years.

The signatures are fairly simple. Simply call barcode with the number of the barcode and the scale of the barcode as an integer. The number needs to be either 12 or 13 digits. The barcode will always be 13 digits even if only 12 are supplied as the 13th digit is the checksum of the first 12. The barcode’s scale will not go lower than 2 for scaling reasons and no higher than 12 for memory reasons. A scale of 4 has worked well for my purposes in the past.

$barcode = new Barcode(1349875921348, 4); $barcode = new Barcode(439457143245, 10); 

The key thing to keep up with is the FreeSansBold.ttf file. By default the Barcode class will look into PHP’s calling directory for the font file. You can specify a path as a third parameter.

$barcode = new Barcode(123456789120, 4, "/path/to/FreeSansBold.ttf"); 

There are only two public methods: image() and display() . The first function image() returns the PHP created image as a reference. This may be used to save an image to file, e.g. imagepng($barcode->image(), «/path/to/storage/barcode.png») . The second function display() simply calls the correct headers and displays the barcode in the browser. Useful for debugging.

About

Источник

Manual — EAN-13

EAN-13 code allows you to encode values to sell products. This code contains 13 numbers but since the last character is a checksum, you must enter only 12 characters. You can enter 13 characters, the last number will be replaced if it doesn’t match the right checksum.

This class inherits the BCGBarcode1D class.

Example
