PHP DataType

How many datatype supported PHP

PHP has a total of eight data types which we use to construct our variables: 

simple types

Simple types

•  Integers: are whole numbers, without a decimal point, like 4195. 
•  Doubles: are floating-point numbers, like 3.14159 or 49.1. 
•  Booleans: have only two possible values either true or false. 
•  NULL: is a special type that only has one value: NULL. 
•  Strings: are sequences of characters, like 'PHP supports string operations.' 

Compound  Type

•  Arrays: are named and indexed collections of other values. 
•  Objects: are instances of programmer-defined classes, which can package up both other kinds of values and functions that are specific to the class. 

The first five are simple types, and the next two (arrays and objects) are compound  -  the 

compound types can package up other arbitrary values of arbitrary type, whereas the simple 

types cannot. 

Resources: are special variables that hold references to resources external to PHP (such as database connections).
