I have some questions about the last statement @ set_time_limit (360.

The set_time_limit function works the same way as modifying max_execution_time in php. ini. Here, the maximum execution time of the script is set to 360 seconds. at first, I saw this statement fall into a misunderstanding: due to the index from the top layer. php sends require all the way to this php, and The require statement will be directly replaced by the file contained in it during execution, so the 360 s limit the execution time of which php is used. When I was puzzled, I saw the word "script". then I suddenly thought that this function was not used to limit the execution time of the PHP file, and the PHP file was not a script file, this function is used to limit the execution time of js and other scripts used in ecshop. forgive me for being unliterate and I am so arrogant.
