[PHP] php判斷http還是https的方法

之前在php判斷http或https只用(isset($_SERVER[‘HTTPS’]) && $_SERVER[‘HTTPS’] == “on”

結果這次失效，把整個$_server印出來之後發現沒有https這個屬性，取而代之的是HTTP_X_FORWARDED_PROTO這個屬性!!

找了一下這個應該是完整版了吧!?

/**
* PHP判断当前协议是否为HTTPS
*/
function is_https() {
if ( !empty($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) !== 'off') {
return true;
} elseif ( isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] === 'https' ) {
return true;
} elseif ( !empty($_SERVER['HTTP_FRONT_END_HTTPS']) && strtolower($_SERVER['HTTP_FRONT_END_HTTPS']) !== 'off') {
return true;
}
return false;
