在php获取一个url地址我会使用到超级全局变量$_SERVER,他包括了各种参数获取,如HTTP_HOST、PHP_SELF、QUERY_STRING等等,这里就不介绍了。
PHP获取URL的几个函数介绍,代码如下:
- <?php
- //获取域名或主机地址
- echo $_SERVER['HTTP_HOST']."<br>";
- //获取网页地址
- echo $_SERVER['PHP_SELF']."<br>";
- //获取网址参数
- echo $_SERVER["QUERY_STRING"]."<br>";
- //来源网页的详细地址
- echo $_SERVER['HTTP_REFERER']."<br>";
- ?>
把上面的几个函数组合一下,即可得到完整的URL地址,代码如下:
- <?php
- // 说明：获取完整URL
- function curPageURL()
- {
- $pageURL = 'http';
- if ($_SERVER["HTTPS"] == "on")
- {
- $pageURL .= "s";
- }
- $pageURL .= "://";
- if ($_SERVER["SERVER_PORT"] != "80")
- {
- $pageURL .= $_SERVER["SERVER_NAME"] . ":" . $_SERVER["SERVER_PORT"] . $_SERVER["REQUEST_URI"];
- }
- else
- {
- $pageURL .= $_SERVER["SERVER_NAME"] . $_SERVER["REQUEST_URI"];
- }
- return $pageURL;
- }
- ?>
定义该函数之后就可以直接调用了,代码如下:
- <?php
- echo curPageURL();
- ?>
