我一直在上下我的代码添加和删除全局变量到函数。
是否可以将全局变量中的全局变量传递给函数,以便在每次函数中保存定义它们?如果不是,有更好的方法吗?
我的目标是在每个页面的顶部放置一个全局变量索引,而不必担心必须在函数内定义它们。
global $site;
$site = "global $link, $create, $populate, $delete, $withdraw";
$host = "";
$username = "";
$password = "";
$database = "";
$link = mysqli_connect("$host", "$username", "$password", "$database");
function display() { global $site; // code }
function populate() { global $site; // code }
function create() { global $site; // code }
function withdraw() { global $site; // code }
//output
答案 0 :(得分:2)
我不确定我是否理解得很好。但是为什么不用$site
和数组而不是字符串?
像这样:
$host = "";
$username = "";
$password = "";
$database = "";
$link = mysqli_connect("$host", "$username", "$password", "$database");
$site = array(
'link' => $link,
'create' => $create,
'populate' => $populate,
'delete' => $delete,
'withdraw' => $withdraw,
);
function display() {
global $site;
// Here you can access & modify your $site array
}
