Hi @yehudat,
For PHP code you have mentioned we have used
_n() function that Translates and retrieves the singular or plural form based on the supplied number.
So It will be localize like following in .po file.
msgid “Highest Current Offer:”
msgid_plural “Highest Current Offers:”
msgstr[0] “”
msgstr[1] “”
It is included in the commit. As per the syntax of _n() function we generally used inside sprintf(). You can see it in example too.
