proc_terminate - Kills a process opened by proc_open

SYNOPSIS
       bool proc_terminate (resource  $process, [int  $signal = 15])

DESCRIPTION
	Signals  a $process (created using proc_open(3)) that it should terminate. proc_terminate(3) returns immediately and does not wait for the
       process to terminate.

       proc_terminate(3) allows you terminate the process and continue with other tasks. You may poll the process (to see if it has  stopped  yet)
       by using the proc_get_status(3) function.

PARAMETERS
	      o $process
		- The proc_open(3) resource that will be closed.

	      o $signal
		-  This  optional  parameter  is only useful on POSIX operating systems; you may specify a signal to send to the process using the
		kill(2) system call. The default is SIGTERM.

RETURN VALUES
	Returns the termination status of the process that was run.
