proc_close
(PHP 4 >= 4.3.0, PHP 5, PHP 7)
proc_close — Close a process opened by proc_open() and return the exit code of that process
Description
proc_close
( resource $process
) : int
proc_close() is similar to pclose() except that it only works on processes opened by proc_open(). proc_close() waits for the process to terminate, and returns its exit code. Open pipes to that process are closed when this function is called, in order to avoid a deadlock - the child process may not be able to exit while the pipes are open.
Return Values
Returns the termination status of the process that was run. In case of
an error then -1 is returned.
Note:
If PHP has been compiled with --enable-sigchild, the return value of this function is undefined.
