取脚本扩展名
<?php /** by www.phpddt.com */ $url = "http://www.phpddt.com/abc/de/fg.php?id=1"; $path = parse_url($url); echo pathinfo($path['path'],PATHINFO_EXTENSION); //php ?>
#测试网址: http://localhost/blog/testurl.php?id=5 //获取域名或主机地址 echo $_SERVER['HTTP_HOST']."<br>"; #localhost //获取网页地址 echo $_SERVER['PHP_SELF']."<br>"; #/blog/testurl.php //获取网址参数 echo $_SERVER["QUERY_STRING"]."<br>"; #id=5 //获取用户代理 echo $_SERVER['HTTP_REFERER']."<br>"; //获取完整的url echo 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; echo 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'].'?'.$_SERVER['QUERY_STRING']; #http://localhost/blog/testurl.php?id=5 //包含端口号的完整url echo 'http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; #http://localhost:80/blog/testurl.php?id=5 //只取路径 $url='http://'.$_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"]; echo dirname($url); #http://localhost/blog
1、利用pathinfo:
<?
$test = pathinfo("http://localhost/index.php");
print_r($test);
?>
结果如下
Array
(
[dirname] => http://localhost //url的路径
[basename] => index.php //完整文件名
[extension] => php //文件名后缀
[filename] => index //文件名
)
2、利用parse_url()函数解析
<?
$test = parse_url("http://localhost/index.php?name=tank&sex=1#top");
print_r($test);
?>
结果如下
Array
(
[scheme] => http //使用什么协议
[host] => localhost //主机名
[path] => /index.php //路径
[query] => name=tank&sex=1 // 所传的参数
[fragment] => top //后面根的锚点
)
3、使用basename()
<?
$test = basename("http://localhost/index.php?name=tank&sex=1#top");
echo $test;
?>
结果如下
index.php?name=tank&sex=1#top
