What are data types in php | PHP datatypes - String,IntegerFloat ,Boolean,Array,Object,NULL,Resource

Variables can store data of different types, and different data types can do different things.

PHP supports the following data types:

String
Integer
Float (floating point numbers - also called double)
Boolean
Array
Object
NULL
Resource

PHP String: A string is a sequence of characters, like "Hello world!". A string can be any text inside quotes. You can use single or double quotes:

PHP Integer: An integer data type is a non-decimal number between -2,147,483,648 and 2,147,483,647.

PHP Float: A float (floating point number) is a number with a decimal point or a number in exponential form.

PHP Boolean: A Boolean represents two possible states: TRUE or FALSE. Booleans are often used in conditional testing.

PHP Array: An array stores multiple values in one single variable.

PHP Object: Classes and objects are the two main aspects of object-oriented programming. A class is a template for objects, and an object is an instance of a class. When the individual objects are created, they inherit all the properties and behaviors from the class, but each object will have different values for the properties.

PHP NULL Value: Null is a special data type which can have only one value: NULL. A variable of data type NULL is a variable that has no value assigned to it.

PHP Resource: The special resource type is not an actual data type. It is the storing of a reference to functions and resources external to PHP.
