Solution to the increasing PHP memory: 1. Open the corresponding PHP file; 2. Change the path in the loop body to an absolute path; 3. Release the variable "$file_dir" and write it directly as "include" ('...');"; 4. Call the shell script to release the memory of the Linux system.

What should I do if php memory keeps increasing?

Specific problem description:

php memory keeps growing problem

There is such a piece of code

set_time_limit(0);
while (true){ $file_dir='data/cache/123.php'; 
include ($file_dir); sleep(1); }

This piece of code It is a never-ending loop code. Now there is a problem. Include will be reloaded every time it loops, and it must be reloaded because each loop requires reading the latest 123.php file, so include_once cannot be used. Problem Right here, every time the 123.php file is loaded in a loop, the memory will increase by 4K. If this continues under high concurrency conditions, the memory will be eaten up in a while. How can we release the memory added by include once in a loop?

Problem analysis and solution:

Why do you put cache and keep including...

This 4k memory may be occupied when the file is opened , you try writing the path in the absolute path...

Release the variable $file_dir and write it directly as include('absolute path to the file');

You can call the shell script after a few seconds of execution Release the memory of the Linux system....I don’t know about win serv....
