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 ==

<pre>
<?php
$msg = "Hello World";
echo $msg;
?>
</pre>

The above example sets the variable named <code>$msg</code> equal to the value "Hello World". (The equal sign ('''=''') is the [[PHP assignment operator]].

The [[PHP text generation|echo]] keyword then displays "Hello World" for the user.
