php - Will a script continue to run even after closing a page?

Question

if i call a php file via jquery ajax, that contains a script to do some stuff that takes a while — for instance uploading a big video — and then I close the page: does the php script keep loading the video or not?

Answer 1

See here: http://php.net/manual/en/function.ignore-user-abort.php

int ignore_user_abort ([ bool $value ] )

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

When running PHP as a command line script, and the script's tty goes away without the script being terminated then the script will die the next time it tries to write anything, unless value is set to TRUE

There also is a PHP configuration option of the same name: http://php.net/manual/en/misc.configuration.php

By default, if you do nothing, according to the PHP manual the default is to abort the script. http://php.net/manual/en/features.connection-handling.php

NECESSARY UPDATE

It seems I (unknowingly) tricked my way to "reputation points", because I did NOT supply the (correct) answer, but here it is now thanks to testing and continued nudging from "mellamokb":

Quote: "Ok, I took a look at the PHP source code and, if I didn't miss anything, I now have the answer. The "ignore_user_abort" flag is only checked when PHP receive an error trying to output something to the user. So, in my understanding, there is no way to interrupt code which doesn't produce any output."

Okay, I wasn't totally off, but it is important to know that it all depends on whether or not your script produced any output!
