PHPでスネークケースとキャメルケースの変換

Last updated at Posted at 2015-04-13

ちょっと必要に駆られて書きました。

<?php

class String
{
    public static function underscore($str)
    {
        return ltrim(strtolower(preg_replace('/[A-Z]/', '_\0', $str)), '_');
    }

    public static function camelize($str)
    {
        return lcfirst(strtr(ucwords(strtr($str, ['_' => ' '])), [' ' => '']));
    }
}
$str1 = 'camelString';
$str2 = 'snake_string';

String::underscore($str1); // => 'camel_string'
String::camelize($str2); // => 'snakeString'

とくに問題なく動くはず。。
