What Are Data Types?
Data types specify the kind of data that a variable can hold. PHP is a dynamically typed language, meaning variables can change their type during execution.
Example:
Key Point: PHP automatically determines the data type of a variable based on its value.
<?php
$value = 42; // Integer
echo $value;
$value = "Hello"; // Now a String
echo $value;
?>
