PHP is both object-oriented and procedural. The official advantage of PHP is that any language construct can be used as an object.
In an object-oriented model, a process is modeled as a collection of objects communicating with each other. The objects are instances of classes, which are also created by the programmer. Each class defines the attributes (data) and methods (procedures) that characterize its instances.

In procedural programming, procedures can be called in any sequence. In object-oriented programming, methods are invoked through reference to an instance of a class that defines these methods.
In a procedural model, the focus is on procedures or functions that operate over data structures. Data and functions are separate entities and generally global to the program.

In an object-oriented language (like PHP), however, objects are created by classes. Classes define both the data structure of their instances (which is called state) and the operations that can be performed on them (which is called behavior). In PHP you can create different instances of a class with different states, but all have access to a common set of behaviors defined by their class.
The main difference between these two programming models is how they deal with data being modified. Object oriented design focuses on data being modified only by its defining class. In contrast, in a functional model modifications to data can come from any context within the program, where the data is accessible.
Let’s look at an example of how these two programming models differ.
We can create a class in PHP with the following code:
class Person {
}
This creates a class called ‘Person’, which is similar to defining a module or namespace in most other languages. Any time we want to use this class, we need to instantiate it with the new keyword and specify what data type will be stored in it. For example:
$person = new Person();
You can then start defining variables within your object:
PHP can be used in either an object oriented way or in a procedural way but it has some differences from other languages in this respect.

PHP is both object-oriented and procedural. It is a hybrid language, though it leans towards OOP. PHP is an example of a multi paradigm language which means that you have many different ways to solve the same problem. For example, if you want to write the string "Hello world", you could do so by using the following:
```php
echo 'Hello world'; // print out hello world as text on your page
echo 'Hello'; // call echo() function and pass in parameter Hello: outputs Hello
// or even better still use sprintf(): this will give consistent results on all platforms and work with numbers as well as strings!
$s = sprintf("%s %s", $name1, $name2); // print name1 followed by name2 with no spaces between them
