How to cancel the execution of a long script through the browser?

Question

PHP

You need to stop the php script from the browser. Restart the server or kill all apache child processes. Tried to do so Result is zero. Probably not enough right. windows OS passthru('C:\Apache24\bin\httpd.exe -k restart');

Answer 1

"Long scripts" should not be run from a browser. System commands too. Reloading should ideally never happen at all.
If the script hangs, then you need to fix the cause, not the consequences.
If we are talking about workflow, then use the event queue, semaphores, data exchange, etc.
