As per the man page for popen() RETURN VALUE The popen function returns NULL if the fork(2) or pipe(2) calls fail, or if it cannot allocate memory. The pclose function returns -1 if wait4 returns an error, or some other error is detected. The PHP code checks for a non-zero (or false) and treats that as an error condition. Since popen() returns -1 on an error the PHP code is correct. -Rasmus
