In the last example the call to ignore_user_abort() is used incorrectly. The manual clearly states that is the first parameter is not given, only the value is returned!
Specify a boolean value like this,
ignore_user_abort(TRUE);
ignore_user_abort
(PHP 4, PHP 5)
ignore_user_abort — Set whether a client disconnect should abort script execution
Descrierea
int ignore_user_abort
([ bool $setting
] )
Sets whether a client disconnect should cause a script to be aborted.
Parametri
- setting
-
If not set, the function will only return the current setting.
Valorile întroarse
Returns the previous setting, as a boolean.
Note
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(); // 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);
?>

"It will return the previous setting" -- not quite. It returns an int, not a bool (as per the syntax description)

I wrote a simple function that can "spawn" another thread within the webserver by making async http request. The page that is being spawned can call ignore_user_abort() and do whatever it wants in the background...
<?php
function http_spawn($page)
{
$basepath=ereg_replace('[^/]*$', '', $_SERVER['PHP_SELF']);
$cbSock=fsockopen('localhost', $_SERVER['SERVER_PORT'], $errno, $errstr, 5);
if ($cbSock)
{
fwrite($cbSock, "GET {$basepath}{$page} HTTP/1.0\r\n"
."Host: {$_SERVER['HTTP_HOST']}\r\n\r\n");
}
}
?>
Example:
<?php
if ($search_initialized)
http_spawn("ftindex.php");
?>

Note that the function name and description seem to be contradictory:
- ignore_user_abort (TRUE, I want to ignore the user's abort request)
- Set whether a client disconnect should abort script execution (TRUE, I want to set this behavior)
The function name is the authoritative one: a value of TRUE will ignore the user's abort.

The script should output something to the browser in order to abort. If there is no output the script keeps on running.
