How can one ensure that the necessary assembly is accessible to PHP when using .Net objects?

To ensure that the necessary assembly is accessible to PHP when using .Net objects, you can use the `clr_add_reference()` function in PHP to load the assembly. This function allows you to specify the path to the assembly file, which will then be available for use in your PHP code.

clr_add_reference('path/to/your/assembly.dll');
