      The <parameter>flags</parameter> parameter controls the behavior
      of the fork. Pass <literal>0</literal> for default behavior or
      <constant>FORK_NOSIGCHLD</constant> to prevent the
      <constant>SIGCHLD</constant> signal from being sent to the parent
      when the child terminates.

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