Description:
------------
The manual for pclose and proc_close states:

Note: Unix Only:

proc_close() is internally implemented using the waitpid(3) system call. To obtain the real exit status code the pcntl_wexitstatus() function should be used.

However, they in fact return the real exit code directly.  This makes it impossible to tell whether a program exited normally or was killed by a signal.


Test script:

Expected result:
----------------
Testing command: false

pclose test:
status value: int(256)
pcntl_wifexited: bool(true)
pcntl_wexitstatus: int(1)
pcntl_wifsignaled: bool(false)
pcntl_wtermsig: int(0)

proc_close test:
status value: int(256)
pcntl_wifexited: bool(true)
pcntl_wexitstatus: int(1)

pcntl_wtermsig: int(0)


Testing command: kill -1 $$

pclose test:
status value: int(1)
pcntl_wifexited: bool(false)
pcntl_wexitstatus: int(0)
