Variable permanent speichern in PHP

So kann man Variable permanent (Laufzeit) speichern.

<?php


myvars( ["city"  => "bonn" ] );
myvars( ["alter" => "33" ] );
myvars( ["auto"  => "bmw" ] );

echo " Stadt: " . myvars("city");
echo " Alter: " . myvars("alter");
echo " Auto: " . myvars("auto");



function myvars( $arr ){
	static $vars;
	
	if( is_array($arr) ){
		$key = key( $arr );
		$vars[ $key ] = $arr[ $key];
	} else {
		return $vars[ $arr];
	}

}

?>
