PHP strftime () function How to output the Chinese version of the week: as of Monday

PHP strftime () function How to output the Chinese version of the week: as of Monday

<?php
SetLocale (Lc_all, "chs.utf-8");
echo "Chinese simple physique Type:". Strftime ("%u");

?>

To run this code, there is no output result in Chinese simple formatting:

<?php
SetLocale (Lc_all, "chs.utf-8");
echo "Chinese simple physique Type:". Strftime ("%A");

?>

Run this code with the result: Chinese Simplified physique: Saturday

I do not know how to debug, before the result can appear: Chinese simple physique: Saturday?
