This library lets you convert a specific to Japan Post Bank account code into a familiar branch name and account number pair.
As simple as this:
composer require sanmai/jpb-account-converter
$converter = new \KigoBangoShiraberu\Converter('14030', '12345671');
var_dump($converter->getAccountType());
var_dump($converter->getBranchName());
var_dump($converter->getBranchNameKana());
var_dump($converter->getAccountNumber());
echo "\n$converter\n";
Sample output:
string(6) "普通"
string(9) "四〇八"
string(18) "ヨンゼロハチ"
string(7) "1234567"
銀行名 ゆうちょ銀行
金融機関コード ９９００
店番 ４０８
預金種目 普通
店名 四〇八店（ヨンゼロハチ店）
口座番号 １２３４５６７
You can confirm its correctness with the original tool from the Japan Post Bank.
Only difference from the original tool is that this library doesn't check a branch number against the list of known branch numbers. Every other check is in place. See the tests.
