PHP script continues after closing / stopping page

Question

Seems php scripts continue even after closing or stopping a page.

for example, if my script is run by /localhost/test.php

after I close the page, sometimes it continues to run. I'm pretty sure restarting apache clears it out but is there a better way to terminate the php script after it's started.

True. But I'm looking for something on the client side to stop the script. — elgato75

Hm... how about a (GET) link to a function with an exit? All that comes to mind. — Funk Forty Niner

You could use ignore_user_abort but I think it only applies if you are running PHP as a command line script .

When running scripts from browser , in my experience I have realized scripts running even after the browser was closed . I did not go further to check how long they used to run .

The scripts that does huge processing that could run many minutes , I used to have control as below :

A flag variable is considered which is stored in a database table .
A way is provided to set the flag On or Off ( or 1 or 0 ) .
The flag is checked in the script and the script is stopped running if the flag is found to be Off ( or 0 ) .

One way to consider the flag is in a loop as below :

while(true)
{
    /* Your code here which probably does lot of processing */

    if($flag === false) break; // Or exit if you prefer
}

If you have code that need to run following the loop , you would use break .
If you want to abruptly stop the script you could use exit instead in its place .

No problem . I have PHP scripts that run in terms of minutes which are tested from a browser initially and later are set as a cron jobs . For my purposes I found it the best way to have control over such scripts . It's good that you found my answer helpful . Cheers ...

check this out: http://php.net/manual/en/function.ignore-user-abort.php

Sets whether a client disconnect should cause a script to be aborted.

the default is set to false (user_aborts are not ignored). and yet it still runs.
