Understanding Data Types in PHP

Data types specify the kind of data a variable can hold. In PHP, common data types include strings, integers, and arrays.

Here are some examples:

// Declaring data types
$name = "Alice";      // String
$age = 25;            // Integer
$balance = 100.50;    // Float
$is_member = true;    // Boolean
$friends = array("Bob", "Charlie"); // Array

Choose the appropriate data type to store values effectively in PHP.
