ignore_user_abort
Description
ignore_user_abort() allows developers to control whether a remote client can abort the running of a script. If the user_abort_setting argument is set to FALSE, client aborts (and some network errors) will cause the script to stop running. If user_abort_setting is set to TRUE, the script continues running until an error occurs, the script finishes execution, or the script times out.
Note
Regardless of the ignore_user_abort() setting, no output will be sent to the client's browser after an attempt to abort the script. See connection_aborted() for information on how to deal with an aborted script.
Example
Example 186. Help a disconnected client resume a session without cookies
// Assume that we are using a system where clients log in
// ...and we know their email addresses
// this should go at the top of the script
ignore_user_abort (TRUE);
// this should go at the bottom of the script
if (connection_aborted () && $user_prefs['resume_session']) {
$message = "Dear $user->name,
It looks like either you lost your connection or pressed
stop while viewing a script at www.e-foo.com. To resume
your session, visit this link:
http://www.e-foo.com/recover_session/" . SID . ".
To avoid receiving these kinds of messages in the future,
please visit http://www.e-foo.com/preferences and disable
the resume connection feature.
Thank You!
The e-foo team";
