PHP Data Types
What are PHP Data Types:
Variables can store different types of data. A data type is a set of values and the allowable operations on those values.
PHP Has Eight data types:
A string is a sequence of characters enclosed inside quotes.
$name = "Robin Kumar"; echo $website;
Generally, we use string to store names, description, and many more things. In this example, we have assigned a person name to variable $name.

Integers are whole numbers that can be used to assign person age, count, calculations and many purposes.
- Numbers can be positive and negative.
- Numbers can not be without fractional part i.e they cannot be decimal numbers.
- The range of an integer or numbers can be between 2,147,483,648 and 2,147,483,647 i.e., -2^31 to 2^31.
PHP Float Data Type
Floating-point numbers represent real numbers in computing. Real numbers measure continuous quantities, like weight, height, or speed. Floating-point numbers in PHP can be larger than integers and they can have a decimal point.
<?php $s = "this is string example"; // $s is a string variable echo $s."<br>"; $i = 10; // $i is an integer variable echo $i."<br>"; $f = 1.3; // $f is now a float (3.3) echo $f."<br>"; $concat_i = $i."10 Little Piggies"; // integer echo $concat_i."<br>"; ?>
