PHP Data Types

PHP supports various data types, including integers, floats, strings, arrays, and objects. PHP variables can hold different types of data.

String: A sequence of characters enclosed in quotes.

E.g., $str = “Hello, World!”;

Integer: Whole numbers. E.g., $num = 42;
Float: Numbers with decimal points. E.g., $price = 19.99;
Boolean: Represents true or false. E.g., $isActive = true;
Array: A collection of values. E.g., $colors = array(“red”, “green”, “blue”);
Object: An instance of a class. E.g., $person = new Person();
NULL: A variable with no value. E.g., $var = NULL;

 

PHP is a dynamically typed language, meaning you don’t need to declare a variable’s type beforehand. The type is determined by the value assigned to it.

Example

<?php

// Integer data type

$age  = 32;

 

// Float data type

$width = 5.9;

//String data type

$name = “John”;

//Boolean data typ

$is_active = true;

?>
