This article summarizes some methods for regularly executing PHP scripts in PHP. There are methods in Linux, Windows, and PHP itself. Friends in need can refer to them.

Execute PHP script regularly under Linux


Execute PHP script

Method 1
If you want to execute a PHP script regularly, you can write it directly like this:
* /1 * * * * root -q /bin/local/php /path/to/your/php/script.php (execute script.php every minute)
Note that writing this way requires making PHP accessible Script file to execute. Under the command line, the directory where the script is located
chmod +x script.php

crontab+php-cgi executes the PHP script regularly

1. Create the requested script index in the web root directory. php

My file path (different paths depending on the installation path): /usr/local/webserver/htdosc/index.php

2. Create a crontab file

2.1 crontab -e

2.2 * * * * * /usr/local/webserver/php/bin/php-cgi -q /usr/local/webserver/htdosc/index.php

#Edit crond plan, request index.php every minute

is completed. After the above steps are completed, my computer can normally request index.php every minute


Notes:

1. /usr/local/webserver/php/ is my php installation path

2. php-cgi is the php parser (this is my understanding, but I always feel that I understand it wrong , hope you guys can correct me), some information is using ./bin/php, which is not available on my computer, so I use php-cgi, maybe the installation method is wrong.

3. -q is the quiet mode (seen in some materials) to run the php script

4. Some materials add #! to the first line of index.php /usr/ local/webserver/php/bin/php -q and add execution permissions to index.php. I didn't do this, and I could request index.php normally


Finally, I will introduce the implementation of a PHP scheduled execution task

The functions used ignore_user_abort(),set_time_limit(0),sleep ($interval)
You only need to run this code once and then close the browser.

The code is as follows
 代码如下 复制代码

ignore_user_abort();//关掉浏览器,PHP脚本也可以继续执行.
set_time_limit(0);// 通过set_time_limit(0)可以让程序无限制的执行下去
$interval=60*30;// 每隔半小时运行
do{
 //这里是你要执行的代码 
 sleep($interval);// 等待5分钟
}while(true);

Copy code
ignore_user_abort();//Close the browser, and the PHP script can continue to execute.
set_time_limit(0);//Through set_time_limit(0), the program can be executed without limit$interval=60*30;//Run every half hour

do{

//Here is the code you want to execute } while(true);

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

What are some common problems that can cause PHP sessions to fail?What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AM

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

How do you debug session-related issues in PHP?How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AM

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

What happens if session_start() is called multiple times?What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How do you configure the session lifetime in PHP?How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
