Variables

Variables hold the data that your program manipulates while it runs, such as information about a user that you've loaded from a database or entries that have been typed into an HTML form. In PHP, variables are denoted by $ followed by the variable's name. To assign a value to a variable, use an equals sign (=). This is known as the assignment operator.

$plates = 5;

$dinner = 'Beef Chow-Fun';

$cost_of_dinner = 8.95;

$cost_of_lunch = $cost_of_dinner;
