What are the limitations of PHP in directly calling functions from a DLL or using a Lib file?

PHP does not have built-in support for directly calling functions from a DLL or using a Lib file. However, you can use the PHP extension "FFI" (Foreign Function Interface) to interact with these shared libraries. FFI allows you to load and call functions from dynamic libraries without the need for writing C extensions. 

// Load the dynamic library
$ffi = FFI::cdef("
    int my_function(int);
", "my_library.dll");

// Call the function from the DLL
$result = $ffi->my_function(42);
echo $result;
