# pcntl_fork

(PHP 4 >= 4.1.0, PHP 5)

pcntl_fork -- Forks the currently running process

## Opis

int pcntl_fork ( void )

The pcntl_fork() 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.

## Zwracane wartości

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.
