I was able to duplicate this as written above. Two notes though:

1) passthru() will work as described above, but the the value stored in the $result will be the exit status of the program. If it is not zero, the program did not run. If it is 127, it could not find the program. As well, passthru() is typically used for binary or raw data: use exec('command','output var','return code') to store the data retrieved form the executed command and system('command','return code') to print string data out as retrieved.

2) the results of those commands are affected by the INI_SYSTEM values of safe_mode and safe_mode_exec_dir. If safe_mode is set to yes, executable are only allowed in the safe_mode_exec_dir.
