Generate a barcode

Examplephp
use OpenBarcode\Linear\UPC;
$bars = (new UPC("03600029145"))->barcode(); // 95 modules

The example encodes UPC-A 03600029145, which gets check digit 2 and produces 95 modules. The same input gives the same modules in every Open Barcode library.

More examples

Each example uses the same modules as the tests, so the output matches the other languages.

Three barcode typesphp
<?php
use OpenBarcode\Linear\{UPC, EAN, Code39};

$upc = (new UPC("03600029145"))->barcode();     // 95 modules
$ean = (new EAN("400638133393"))->barcode();    // 95 modules
$code39 = (new Code39("CODE39"))->barcode();    // 103 modules
Wrong check digitphp
<?php
use OpenBarcode\Linear\UPC;

try {
    new UPC("036000291453"); // the check digit should be 2
} catch (InvalidArgumentException $e) {
    echo $e->getMessage();
}
