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 byproc_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.
