### Описание

int ignore_user_abort ([ string `$setting` ] )

### Список параметров

  If not set, the function will only return the current setting.

### Возвращаемые значения

Returns the previous setting, as a boolean.

### Примеры

Пример #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.
?>`

### Примечания

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().
