php判断当前服务http还是https

php判断网络协议请求类型是http还是https的方法如下：

<?php 
function getRequestType(){
	$type = 'http://';
	if(((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') || (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https'))){
		$type = 'https://';
	}
	return $type;
}
?>

条件太长不方便看可以这样：

<?php
function getRequestType(){
	$type = 'http://';
	$term1 = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') == true;
	$term2 = (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https') == true;
	if($term1 || $term2){
		$type = 'https://';
	}
	return $type;
}
?>

你还可以这样：

<?php
$httpType = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') || (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https')) ? 'https://' : 'http://';
?>

如果是解析已有的url连接，方法如下：

$httpType = strpos($url,'https://') !== false ? 'https://' : 'http://';
