ランダムな英数字を組み合わせたパスワードを生成したい。
自分で作っても良かったのだけど、面倒くさかったので探してみた。
CakePHPのバージョン1の頃に含まれていたらしいライブラリにそれっぽいのがあったのでサルベージ
http://api11.cakephp.org/neat__string_8php-sourch.html
ところで、なんでこのライブラリは外されたんだろう。なんか有りそうな気がするけど
使用例？
CakePHPで使うには、上記のライブラリをvendorsに放り込んで呼び出してみる
App::import('Vendor', 'NeatString');
$password = NeatString::randomPassword(8);
neat_string.php
気がつくと無くなりそうなので、一応転記しておく
