That isn't a particularly good use case for FFI. If you're trying to call
Python scripts, you're probably looking for popen(), proc_open(), or something
like the Symfony Process component (composer require symfony/process).
FFI allows PHP scripts to load and call functions in C libraries. This can
allow PHP scripts to access functionality which doesn't have PHP wrappers
available.
If you're on macOS, here's a silly but functional example which calls the
NSBeep() function to make your computer beep:
$ffi = FFI::cdef(<<<'EOF'
void NSBeep(void);
EOF, "@rpath/AppKit.framework/AppKit");
$ffi->NSBeep();
sleep(1);
(Don't worry too much about the @rpath bit.)
