Creating and Using Variables in PHP

Variables are used to store and manipulate values in PHP. They are defined using the dollar sign ($), followed by the variable name.


$variable_name = value;
Parameter Description

value The value to be stored in the variable.

Here are some examples of using variables in PHP:

		$name = "John Doe";
		$age = 25;

		$isEmployed = true;

		echo "My name is " . $name . ", I am " . $age . " years old.";
