I know this is a bit old question and with a solution voted but I though I should share another option and just found a better solution (that works) without using Globals

function fn_your_var_storage( $var = NULL )
{
    static $internal;

    if ( NULL !== $var )
    {
        $internal = $var;
    }

    return $internal;
}

// store the value
fn_your_var_storage( 'my_value' );

// retrieve value
echo fn_your_var_storage(); // print my_value
