Yes $Clint_ip is an variable,

  1. Like other object oriented based programming languages $this is the this of a class consisting it. (For more about this When to use self over $this?)
  2. request looks like an object of another class
  3. and clintIp() is the public method of the class of the request object

The code you provided appears to be from inside of a class.

A class is denoted like this: 

class Example {
    private $foo;
    public $bar;

    public function __construct() {

    }

    public function method() {

    }

    private function other() {

    }
}

When you create an object of this class, you can use the format:

$example = new Example();

This calls the constructor __construct().

Once you have created ("instantiated") this object, you can use the -> to call the properties of the object.

So, I can say

$example->bar = "Foo";

which sets this property to a string.

Your Code

In your code, the property "request" is itself an object (an instance of a class).

$Clint_ip=$this->request->clintIp();

Here is an example of the code this could be using

class Example {
    public $request;

    public function __construct($request) {
        $this->request = $request;
    }

}

class Request {
    public function clintIp() {
        //return something
    }
}

And then some context:

$request = new Request;
$example = new Example($request);

$clint_ip = $example->request->clintIp();

So here, $clint_ip is the variable. $example and $request are objects (instances of classes), and clintIp() is a method of the request object.

Now, about "$this". This indicates that it is within the object "Example":

Imagine the class Example now has a method

public function test() {
    return $this->request->clintIp();
}

$this means that it is inside of an instance of an object. In static context, use "self::", as mentioned in one of the other answers.

You are inside object which has request property. Request property contains object with method clintIp() which return client ip.
