ignore_user_abort — Set whether a client disconnect should abort script execution
DescriptionWhen 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 enable is set to true
enable
If set and not null, this function will set the ignore_user_abort ini setting to the given enable. Otherwise, this function will only return the previous setting without changing it.
Returns the previous setting, as an integer.
Changelog Version Description 8.0.0enable is nullable now. Examples
Example #1 A ignore_user_abort() example
<?php
// Ignore user aborts and allow the script
// to run forever
ignore_user_abort(true);
set_time_limit(0);
echo
'Testing connection handling in PHP';// Run a pointless loop that sometime
// hopefully will make us click away from
// page or click the "Stop" button.
while(1)
{
// Did the connection fail?
if(connection_status() != CONNECTION_NORMAL)
{
break;
}// Sleep for 10 seconds
sleep(10);
}// If this is reached, then the 'break'
// was triggered from inside the while loop
// So here we can log, or perform any other tasks
// we need without actually being dependent on the
// browser.
?> Notes
PHP will not detect that the user has aborted the connection until an attempt is made to send information to the client. Simply using an echo statement does not guarantee that information is sent, see flush().
