pcntl_forkPodręcznik PHPPoprzedniNastępnypcntl_fork (PHP 4 >= 4.1.0)pcntl_fork -- Forks the currently running processDescriptionint pcntl_fork ( void)
The pcntl_fork() function creates a child
process that differs from the parent process only in it's PID and
PPID. Please see your system's fork(2) man page for specific details as to
how fork works on your system.
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.
