proc_get_status — Get information about a process opened by proc_open()

proc_get_status(resource $process): array

proc_get_status() fetches data about a process opened using proc_open().

An array of collected information. The returned array contains the following elements:

element	type	description
command	string	The command string that was passed to proc_open().
pid	int	process id
running	bool	`true` if the process is still running, `false` if it has terminated.
signaled	bool	`true` if the child process has been terminated by an uncaught signal. Always set to `false` on Windows.
stopped	bool	`true` if the child process has been stopped by a signal. Always set to `false` on Windows.
exitcode	int	The exit code returned by the process (which is only meaningful if `running` is `false`). Prior to PHP 8.3.0, only the first call of this function returned the real value, the following calls returned `-1`.
cached	bool	As of PHP 8.3.0, this is `true` when the exit code is cached. Caching is necessary to make sure the exit code is not lost by subsequent calls to process APIs.
termsig	int	The number of the signal that caused the child process to terminate its execution (only meaningful if `signaled` is `true`).
stopsig	int	The number of the signal that caused the child process to stop its execution (only meaningful if `stopped` is `true`).

Version	Description
8.3.0	The `"cached"` entry has been added to the returned array. Prior to PHP 8.3.0, only the first call returned the real exit code. The `"cached"` entry indicates that the exit code was cached.
