I am looking to have the user submit some information from a form to a page. But I want to do some other stuff after getting the info but I don't want to have the user wait around.
Is there a way to have the user think that the page has finished while still having PHP execute the script?
That is certainly doable. You can use ob_flush() to continue the session. I have an example snippet here: https://snippetbox.xyz/9eb54a2a1f52dc1f5d38/
Pulled from that URL:
This will disconnect the user while the script is still processing
<?php ob_end_clean(); header("Connection: close"); ignore_user_abort(); // optional ob_start(); echo ('Text the user will see'); $size = ob_get_length(); header("Content-Length: $size"); ob_end_flush(); // Strange behaviour, will not work flush(); // Unless both are called ! session_write_close(); // Added a line suggested in the comment // Do processing here sleep(30); echo('Text user will never see'); ?>
