Is there an way to use Operator Overloading in PHP?
I use PHP Version 7.1.
Well PHP doesn't support Operator Overloading altho I'd recommend looking at the thread bellow to read about possible similar solutions
Is it possible to overload operators in PHP?
But bare in mind, PHP's concept of overloading is no where similar to C++

I've been using PHP for some basics Back-End development for a while now. I saw something about interpretations of variables while I was looking for some changes which came with PHP 7. I'm not using them and it would be great if someone can explain why to use them?
What I mean is:
What are the pros of using them?
You use variable interpretation in situations when you need to dynamically reference a variable and don't want to use an array. Generally I would not recommend using it, as you lose benefits such as static code analysis.

What might be some benefits of array type hinting in methods and functions in PHP besides documentation and readability?
Generally, the sooner you catch an error the easier it is to diagnose. Type hinging in php allows those errors to occur earlier than if something does wrong down in the function or in functions that it calls.

I have a library written in C that in turn is build upon the GMP library.
I want to know how can I use the library with PHP?
more informally, say I want to use such library with JAVA, I can simply write Java wrappers for the library.
I think php's exec or shell_exec functions can help you out ...
this functions are used for Execute an external program
take a look at this...

I am developing a PHP website/app that needs to be available in all languages. I intend using the Gettext() method. I need to know how to get through fast ?
Look at tutorials and the gettext documentation and then ask for help when you encounter any obstacles.
Here you have an example from Sitepoint that I think will be helpful: http://www.sitepoint.com/localizing-php-applications-1/

How can i list the all functions i used in my site using php?I used a lot of php functions in my site.If there is any php function to check which functions are used in my site?
Check out doxygen. By running those scripts you will be able to list all functions and classes, and it links them so you can see the usage:

You can look into running a phpxref on your codebase.
