PHP is still commonly used, and I believe everyone knows its benefits. I will show you a PHP file upload code. Let’s take a look. Use the memory_limit variable to specify the maximum memory capacity that a single script program can use. The value of the variable memory_limit should be appropriately greater than the value of post_max_size max_execution_time. max_execution_time sets the time that PHP waits for the script to be executed before forcibly terminating the script. This time is calculated in seconds.

This variable is useful when the script enters an infinite loop. However, this feature can also cause the operation to fail when there is a legitimate activity that takes a long time to complete (such as uploading a large file). In such cases, you must consider increasing the value of this variable to prevent PHP from shutting down the script when the script is executing some important processes. For Linux hosts, it may be under /etc/httpd/conf.d/access.conf/ There is also the php.conf file, which may solve the file size limit problem of some systems.
