In multilingual websites developers may need to print the dates in different languages.
Suppose you would like to print the dates in German language then you may do the following:
<?php
setlocale(LC_ALL, ‘de_DE@euro’, ‘de_DE’, ‘deu_deu’);
echo strftime(“%A”,strtotime($date));
?>
That will print Mittwoch,Donnerstag,Montag in german languages .
