PHP 四种URL解析处理方式的例子

<?php
$test = pathinfo("http://localhost/index.php");
print_r($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 
 ) 
*/
?>

<?php
$test = parse_url("http://localhost/index.php?name=tank&sex=1#top");
    print_r($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
    )
    */
?>

<?php
    $test = basename("http://localhost/index.php?name=tank&sex=1#top"); 
echo $test;
/*
结果如下
index.php?name=tank&sex=1#top
*/
?>

<?php
preg_match_all("/(\w+=\w+)(#\w+)?/i", "http://localhost/index.php?name=tank&sex=1#top", $match);
print_r($match);
/*
结果如下
Array
(
[0] => Array
(
[0] => name=tank
[1] => sex=1#top
)
[1] => Array
(
[0] => name=tank
[1] => sex=1
)
[2] => Array
(
[0] =>
[1] => #top
)
)
