proc_terminate

(PHP 5)

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. However this is only possible with PHP 5.2.2 or newer, as previous versions destroyed the given process resource .

参数

process: The proc_open() resource that will be closed.
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.

返回值

Returns the termination status of the process that was run.
