php执行链接页面

Question

I would to do this :

$timeInit = microtime(true);
$bdd = connexionBase();

function ajuste() {
    header('location:ajusteDateFin.php');
}

function transforme() {
    header('location:moulinetteHsConvertionCodeArticle.php');
}

ajuste();
transforme();
echo "<br><br>";
echo microtime(true)-$timeInit;

But with this code, only the transforme() page is executed. Is there a way to chain them.
