Description détaillée

Class to turn CliApplication applications into daemons. It requires CLI and PCNTL support built into PHP.

https://www.php.net/manual/en/features.commandline.php 1.7.0

Documentation des constructeurs et destructeur

__construct()

__construct	(	\JInputCli	$input = null,
		Registry	$config = null,
		\JEventDispatcher	$dispatcher = null
	)

Class constructor.

Paramètres

\JInputCli	$input	An optional argument to provide dependency injection for the application's input object. If the argument is a object that object will become the application's input object, otherwise a default input object is created.
Registry	$config	An optional argument to provide dependency injection for the application's config object. If the argument is a Registry object that object will become the application's config object, otherwise a default config object is created.
\JEventDispatcher	$dispatcher	An optional argument to provide dependency injection for the application's event dispatcher. If the argument is a object that object will become the application's event dispatcher, if it is null then the default event dispatcher will be created based on the application's loadDispatcher() method.

gc()

gc ( )

loadConfiguration()

loadConfiguration

(

$data

)

Load an object or array into the application configuration object.

pcntlChildExitStatus()

pcntlChildExitStatus (   $status )

protected

Method to return the exit code of a terminated child process.

pcntlFork()

pcntlFork ( )

protected

Method to return the exit code of a terminated child process.

Renvoie

integer On success, the PID of the child process is returned in the parent's thread of execution, and a 0 is returned in the child's thread of execution. On failure, a -1 will be returned in the parent's context, no child process will be created, and a PHP error is raised.
