README

A PHP class for checking EAN8, EAN13, UPC and GTIN barcodes are valid (based on check digit).

https://packagist.org/packages/violuke/php-barcodes

Note: This project currently does nothing other than have some validation functions. I expect to add additional functionality in the future.

Installation (with composer)

composer require violuke/php-barcodes

Usage

// Class instantation
$barcode = '5060411950139';
$bc_validator = new \violuke\Barcodes\BarcodeValidator($barcode);


// Check barcode is in valid format
if ($bc_validator->isValid()) {
	echo 'Valid :)';
} else {
	echo 'Invalid :(';
}


// Get the barcode type
echo 'Barcode is in format of ' . $bc_validator->getType();
// Possible formats returned are:
// (string) "GTIN" which equals constant \violuke\Barcodes\BarcodeValidator::TYPE_GTIN
// (string) "EAN-8" which equals constant \violuke\Barcodes\BarcodeValidator::TYPE_EAN_8
// (string) "EAN" which equals constant \violuke\Barcodes\BarcodeValidator::TYPE_EAN
// (string) "EAN Restricted" which equals constant \violuke\Barcodes\BarcodeValidator::TYPE_EAN_RESTRICTED
// (string) "UPC" which equals constant \violuke\Barcodes\BarcodeValidator::TYPE_UPC
// (string) "UPC Coupon Code" which equals constant \violuke\Barcodes\BarcodeValidator::TYPE_UPC_COUPON_CODE


// Returns the barcode in GTIN-14 format
$bc_validator->getGTIN14()


// Returns the barcode as entered
$bc_validator->getBarcode()

• Barcode generation
• GS1-128 barcode generation and interpretation

Credits

• The barcode validation function was based on work by Ferry Bouwhuis.
• EAN Restricted format added from the hassel-it/php-barcodes fork.
• Initial unit tests based on work in the hassel-it/php-barcodes fork.
