A support class to pluralise English words in Magento

我写这个类更多地是为了补习一下英文。顺便说一下,我会逐渐把更多的 support classes 归于 Msdk module,意思是 Magento SDK.

An ideal way to learn IT and English as a foreign language at a time.


<?php

//if english
return self::english($nr, $singularWord, 's');
}

public static function english($nr, $singularWord, $pluralSuffix = 's') {
if (abs($nr) == 1) {
return "$nr $singularWord";
}
