In PHP, there are eight data types that are utilized to create variables:
1.Integers, such as 4195, are entire numbers without a decimal point.
2.Floating-point numbers, such as 3.14159 or 49.1, are known as doubles.
3.True or false are the only two possible values for Booleans.
4.NULL is a unique type with only one value: NULL.
5.Strings are character sequences, such as ‘PHP supports string operations.’
6.Arrays are collections of other values that are named and indexed.
7.Objects are instances of programmer-defined classes that can bundle up both other types of values and class-specific functions.
8.Resources are unique variables that store references to resources outside of PHP.
