In form, send the text of the new page to php per post:

<form method="post" action="caminho/config.php">
    <input type="text" name="titulo">
</form>

In the config.php page, check if the post exists and if it is not empty, then assign its value to the variable:

if(isset($_POST["titulo"]) && $_POST["titulo"] != "")
    $CONFIG["SiteTitle"] = $_POST["titulo"];
