safer process call

This package directly exec command, not using 'shell'.

proc_open executes command directly, without shell ( fork then exec ).

Don't escape string , use array.

use cmd array. not escaping.

proc_open can accept cmd string, but cmd string may be danger(mal-escaping). exec cmd by array is more safe.

To prevent directory traversal. you must check args in advance. cmd string cannot be checked, but array can check.

pipe by pure php. It's very painful.

Linux pipe max.

Linux pipe will be blocked if left unread.

LINUX_PIPE_SIZE is 1024*64. so if you try to write one more byte (1024*64+1bytes) to stdout, process will be blocked by OS.

Or use select syscall and read the buffer.
