Validate a [Postal Index Number][wiki] for India with a regex. The regexes are available in `regex.txt`. There are 2 regexes. The first validates PINs starting from 1-4, and the second validates the ones starting from 5-8. The reason for the split is to keep the regex size small. Currently they are both at 16K each.
@ -10,6 +10,17 @@ The source for the data is the ["All India Pincode Directory"](https://data.gov.
The `regex.txt` file is 32KB in size, so you can easily use it wherever you want, including browsers.
The package is available on [`packagist`](https://packagist.org/packages/captn3m0/pincode).
To use the PHP package:
use PIN\Validator as P;
P::validate('110011'); // returns true;
