php使用函数pathinfo()、parse_url()和basename()解析URL

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

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)

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

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)

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

index.php?name=tank&sex=1#top
