What is dynamic typing

Dynamic typing is a programming language characteristic where the type of a variable is determined at runtime rather than at compile-time. This means that variables can be assigned and reassigned values of different types throughout the program's execution.

In dynamically typed languages, you do not need to explicitly declare the type of a variable when you create it. This offers great flexibility but can lead to runtime errors if types are not managed carefully.

Here is an example of dynamic typing in PHP:

$variable = "Hello, World!"; // String assignment echo $variable; // Output: Hello, World! $variable = 100; // Now, $variable is an integer echo $variable; // Output: 100 $variable = 10.5; // And now it's a float echo $variable; // Output: 10.5
