PHP date and time application 6: Check whether a date is a weekend

In the previous article "PHP date and time application five: Get the current date/time in different time zones and locations", I introduced you to the methods of obtaining time in different time zones. Next, I will continue to introduce you to the PHP date. The use of time, that is, how to determine whether a date is a weekend.

The theme of this article is to determine whether a date is a weekend, and weekend actually refers to Saturday to Sunday evening. After the implementation of the five-day work system, it refers to Saturday and Sunday every week. Presumably everyone already has an idea of ​​​​judgment.

Before introducing the method, let me share with you a little English knowledge~

Monday: Monday, the English abbreviation Mon.

Tuesday: Tuesday, English abbreviation Tue.

Wednesday: Wednesday, the English abbreviation Wed.

Thursday: Thursday, English abbreviation Thur.

Friday: Friday, the English abbreviation Fri.

Saturday: Saturday, the English abbreviation Sat.

Sunday: Sunday, the English abbreviation Sun.

Let’s go directly to the PHP code:

<?php
$dt=&#39;2021-08-03&#39;;
$dt1 = strtotime($dt);
$dt2 = date("l", $dt1);
$dt3 = strtolower($dt2);
if(($dt3 == "saturday" )|| ($dt3 == "sunday"))
{
    echo $dt3.&#39; 是周末&#39;."\n";
}
else
{
    echo $dt3.&#39; 不是周末&#39;."\n";
}

The running result is:

Obviously Tuesday is not the weekend~

Then let’s give a new date:

<?php
$dt=&#39;2021-08-08&#39;;
$dt1 = strtotime($dt);
$dt2 = date("l", $dt1);
$dt3 = strtolower($dt2);
if(($dt3 == "saturday" )|| ($dt3 == "sunday"))
{
    echo $dt3.&#39; 是周末&#39;."\n";
}
else
{
    echo $dt3.&#39; 不是周末&#39;."\n";
}

The result is:

Sunday is the weekend.

Isn’t it very simple~

A brief analysis of several key functions:

strtotime() Function: convert any English text The date or time description resolves to a Unix timestamp (number of seconds since January 1 1970 00:00:00 GMT).

strtolower()Function: Convert string to lowercase.

date()Function: Format local date and time and return the formatted date string.
