A variable is a name for a data storage location. A variable contains a value.
In PHP, variables begin with a dollar sign ($).
Some variables are built into PHP.
Other variables are defined by the programmer.
Example
<?php $msg = "Hello World"; echo $msg; ?>
The above example sets the variable named $msg equal to the value "Hello World". (The equal sign (=) is the PHP assignment operator.
The echo keyword then displays "Hello World" for the user.
