proc_terminate — Kills a process opened by proc_open
说明bool proc_terminate ( resource $process [, int $signal = 15 ] )
Signals a process (created using proc_open()) that it should terminate. proc_terminate() returns immediately and does not wait for the process to terminate.
proc_terminate() 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() function.
Returns the termination status of the process that was run.
