ignore_user_abort

(PHP 4, PHP 5)

ignore_user_abort — Set whether a client disconnect should abort script execution

Описание

int ignore_user_abort ([ bool $setting ] )

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

Список параметров

setting

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

Возвращаемые значения

Returns the previous setting, as a boolean.

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().

If you want to simulate a crontask you must call this script once and it will keep running forever (during server uptime) in the background while "doing something" every specified seconds (= $interval):

<?php
ignore_user_abort
(1); // run script in background
set_time_limit(0); // run script forever
$interval=60*15// do every 15 minutes...
do{
   
// add the script that has to be ran every 15 minutes here
   // ...
   
sleep($interval); // wait 15 minutes
}while(true);
?>

use the spiritual-coder's code below with exreme caution and do not use it unless you are an advanced user.

first of all, such a code with no bypass point can cause infinite loops and ghost threads in server. there must be a trick to break out the loop. 

i.e. you can use  if (file_exists(dirname(__FILE__)."stop.txt")) break; in the loop so if you create "stop.txt", she script will stop execution.

also if you use set_time_limit(86400); instead of set_time_limit(0); your script will stop after one day.

Comment from Anonymous is not 100% valid. Time from sleep function is not counted to execution time because sleep delays program execution (see function.sleep and comments). We tested it and it's true. Try this:

<?php

set_time_limit
(2);
sleep(4);
echo 
'hi!';
sleep(4);
echo 
'bye bye!';

?>

It means, that if the loop most of the time will be at sleep (and in this case it probably be), then this script may be active for months or years even if you set time limit to one day.

It seems that this function does not work for IIS servers.
