How to set the execution time of PHP under PHP-Fcgi_PHP tutorial
Generally, set the PHP script execution timeout
1. Set in php.ini
max_execution_time = 1800;
2. Set through PHP’s ini_set function
ini_set("max_execution_time", "1800");
3. Set through the set_time_limit function
set_time_limit(1800);
How to set the execution time of PHP under PHP-Fcgi
Yesterday, a program needed to export 500 pieces of data. It was found that 150 pieces of data were exported, and Nginx reported a 504 Gateway Timeout error
After observation, it was found that the timeout occurs at about 30 seconds, and the execution time configuration in php.ini is already 300 seconds:
Checking the relevant configuration of nginx again, to no avail.
Write a php test page and test again
echo 'aaa';
set_time_limit(0);
sleep( 40);
echo 'aa';
It still times out. It can be determined that the set_time_limit function does not take effect.
Check the configuration php-fpm.conf of php-fcgi again, there seems to be a problem with the setting below
Check the official documentation: http://php-fpm.org/wiki/Configuration_File
request_terminate_timeout - The timeout (in seconds) for serving a single request after which the worker process will be terminated. Should be used when 'max_execution_time' ini option does not stop script execution for some reason. Default: "5s". Note: '0s' means 'off'
The general idea is that if php has not been executed within the time set by set_time_limit in php, then the configuration here will be used, that is, request_terminate_timeout=30 seconds.
First change this parameter to be the same as the set_time_limit value in php, which is 300 seconds. It still doesn’t work. I don’t understand why. If an expert knows, please let me know.
Finally, request_terminate_timeout is turned off, the program can be executed normally, and the problem is solved
Supplement: If the front-end nginx server uses upstream load balancing, the following parameters in the load balancing configuration also need to be modified accordingly
proxy_connect_timeout 300s;
proxy_send_timeout 300s;
proxy_read_ timeout 300s;

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.

The steps to build an efficient shopping cart system using sessions include: 1) Understand the definition and function of the session. The session is a server-side storage mechanism used to maintain user status across requests; 2) Implement basic session management, such as adding products to the shopping cart; 3) Expand to advanced usage, supporting product quantity management and deletion; 4) Optimize performance and security, by persisting session data and using secure session identifiers.
