HomeBackend DevelopmentPHP TutorialPHP method to obtain the timestamps of the current month and the beginning and end of the previous month

This article mainly introduces the method of PHP to obtain the timestamps of the current month and the beginning and end of the previous month. It involves PHP's judgment and operation skills related to date and time. Friends in need can refer to the following

for details As follows:

Current month

<?php
$thismonth = date(&#39;m&#39;);
$thisyear = date(&#39;Y&#39;);
$startDay = $thisyear . &#39;-&#39; . $thismonth . &#39;-1&#39;;
$endDay = $thisyear . &#39;-&#39; . $thismonth . &#39;-&#39; . date(&#39;t&#39;, strtotime($startDay));
$b_time  = strtotime($startDay);//当前月的月初时间戳
$e_time  = strtotime($endDay);//当前月的月末时间戳

Previous month

<?php
$thismonth = date(&#39;m&#39;);
$thisyear = date(&#39;Y&#39;);
if ($thismonth == 1) {
 $lastmonth = 12;
 $lastyear = $thisyear - 1;
} else {
 $lastmonth = $thismonth - 1;
 $lastyear = $thisyear;
}
$lastStartDay = $lastyear . &#39;-&#39; . $lastmonth . &#39;-1&#39;;
$lastEndDay = $lastyear . &#39;-&#39; . $lastmonth . &#39;-&#39; . date(&#39;t&#39;, strtotime($lastStartDay));
$b_time = strtotime($lastStartDay);//上个月的月初时间戳
$e_time = strtotime($lastEndDay);//上个月的月末时间戳

The key here is t in the date function, which is used to obtain the number of days in the current month, 28 days, 29 days, 30 days, and 31 days. The number of days it contains is the number at the end of the month.

The above is the entire content of this article, I hope it will be helpful to everyone's study.

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
