<para>
|
|
The <function>pcntl_fork</function> 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.
|
|
</para>
|
|
<para>
|
|
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.
