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 — Establecer si la desconexión de un cliente debe abortar la ejecución del script
Descripción
int ignore_user_abort
([ bool $valor
] )
Establece si la desconexión de un cliente debe causar que el script sea abortado.
Lista de parámetros
- valor
-
Si no se define, la función solo devolverá el valor actual.
Valores retornados
Devuelve el valor anterior, como un valor booleano.
Notes
PHP no detectará que el usuario ha abortado la conexión hasta que se realice un intento de enviar información al cliente. No basta con una sentencia echo para garantizar que se envíe información, vea 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.
