pcntl_fork
PCNTL_FORK(3) 1 PCNTL_FORK(3)pcntl_fork - Forks the currently running processSYNOPSIS
int pcntl_fork (void )
DESCRIPTION
The pcntl_fork(3) function creates a child process that differs from the parent process only in its PID and PPID. Please see your system's
fork(2) man page for specific details as to how fork works on your system.
RETURN VALUES
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.
EXAMPLES
Example #1
pcntl_fork(3) example
<?php
$pid = pcntl_fork();
if ($pid == -1) {
die('could not fork');
} else if ($pid) {
// we are the parent
pcntl_wait($status); //Protect against Zombie children
} else {
// we are the child
}
?>
