In this paper, an example is given to describe the common method of obtaining the day of the week by PHP. Share it for your reference, as follows:

PHP Day of the week to get the code: 


date("l");
//data You can get English weeks, such as Sunday
date("w");
// This can get digital weeks, such as 123 , attention 0 It's Sunday

Get the day of the week in Chinese: 


$weekarray=array(" Day ","1","2","3","4","5","6");
// Define first 1 Array of numbers 
echo " Week ".$weekarray[date("w")];
// Output: Week 2

Gets the specified date as: 


$weekarray=array(" Day ","1","2","3","4","5","6");
echo " Week ".$weekarray[date("w",strtotime("2018-12-18"))];
