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.

Syntax

$variable_name = value;
Parameter Description
variable_name The name of the variable to be created.
value The value to be stored in the variable.

Here are some examples of using variables in PHP:

		$name = "John Doe";
		$age = 25;
		$salary = 1000.50;
		$isEmployed = true;

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

Technical Details

Data Types PHP supports a variety of data types, including strings, integers, floating point numbers, boolean values, arrays, and objects.
Variable Names Variable names in PHP must start with a letter or underscore (_), and can only contain letters, numbers, and underscores.
