How do I implement a variable variable?

A variable variable allows you to have a variable name that is set at
run time.  This can be implemented as follows:

    <?php

    // Set the variable name
    $var_name = 'myvariable';

    // Now you can access the variable $myvariable with
    $$var_name = 1;

    // So this will always work
    if ($$var_name == $myvariable) {
        echo "This will always be true since they are the same thing";
    }

    ?>
