CODABAR not working

[robertmylne]

When I copy and paste your example:

$generator = new Picqer\Barcode\BarcodeGeneratorHTML();
echo $generator->getBarcode('081231723897', $generator::TYPE_CODE_128);

Everything works great. But when I change the barcode type to codabar it breaks.

$generator = new Picqer\Barcode\BarcodeGeneratorHTML();
echo $generator->getBarcode('081231723897', $generator::TYPE_CODABAR);

With this error:

Line 2038: vendor\picqer\php-barcode-generator\src\BarcodeGenerator.php
ErrorException (E_NOTICE)
Uninitialized string offset: 8

I am a bit lost of how to resolve this issue, do you have any ideas? Thank you :)

This works fine here with PHP 7.3. Which PHP version do you use?

It looks like the 2nd char in the code (8) is casted to an integer somewhere, and then it is strictly checked with the possible chars in the array, which only contains the string '8'. But I cannot reproduce this situation.

I added an extra check for this in d96798a, which will be included in the upcoming version. That could fix something like this, but seems illogical to me.

I used a forked package of yours and it worked for me. Thanks anyway.
