你可以这样做,但抱歉我的英语不够好。
首先,用这个简单的代码获取家庭基地网址..
我已经在本地服务器和公共服务器上测试了这段代码,结果很好。
<?php
function home_base_url(){
// first get http protocol if http or https
$base_url = (isset($_SERVER['HTTPS']) &&
$_SERVER['HTTPS']!='off') ? 'https://' : 'http://';
// get default website root directory
$tmpURL = dirname(__FILE__);
// when use dirname(__FILE__) will return value like this "C:\xampp\htdocs\my_website",
//convert value to http url use string replace,
// replace any backslashes to slash in this case use chr value "92"
$tmpURL = str_replace(chr(92),'/',$tmpURL);
// now replace any same string in $tmpURL value to null or ''
// and will return value like /localhost/my_website/ or just /my_website/
$tmpURL = str_replace($_SERVER['DOCUMENT_ROOT'],'',$tmpURL);
// delete any slash character in first and last of value
$tmpURL = ltrim($tmpURL,'/');
$tmpURL = rtrim($tmpURL, '/');
// check again if we find any slash string in value then we can assume its local machine
if (strpos($tmpURL,'/')){
// explode that value and take only first value
$tmpURL = explode('/',$tmpURL);
$tmpURL = $tmpURL[0];
}
// now last steps
// assign protocol in first value
if ($tmpURL !== $_SERVER['HTTP_HOST'])
// if protocol its http then like this
$base_url .= $_SERVER['HTTP_HOST'].'/'.$tmpURL.'/';
else
// else if protocol is https
$base_url .= $tmpURL.'/';
// give return value
return $base_url;
}
?>
// and test it
echo home_base_url();
输出会是这样的:
local machine : http://localhost/my_website/ or https://myhost/my_website
public : http://www.my_website.com/ or https://www.my_website.com/
在您网站的index.php 处使用home_base_url 函数并定义它
然后你可以使用这个函数通过url加载脚本、css和内容
<?php
echo '<script type="text/javascript" src="'.home_base_url().'js/script.js"></script>'."\n";
?>
将创建这样的输出:
<script type="text/javascript" src="http://www.my_website.com/js/script.js"></script>
如果这个脚本运行良好,,!
