PHP的parse_url反向-解析的URL [英] php parse_url reverse -- parsed url

问题描述

是否有一种方法可以从解析的网址中还原网址?

Is there a way to reverse the url from a parsed url?

$url = 'http://www.domain.com/dir/index.php?query=blabla#more_bla';
$parse = parse_url($url);
print_r($parse);
/*
array(
 'scheme'=>'http://',
 etc....
)
*/
$revere = reverse_url($parse); // probably does not exist but u get the point

echo $reverse;
//outputs:// "http://www.domain.com/dir/index.php?query=blabla#more_bla"

或者如果有一种方法可以验证缺少推荐网址部分的网址，例如

Or if there is a way validate a url that is missing part of its recommended urls e.g

www.mydomain.com

mydomain.com

应该全部返回 http://www.mydomain.com 或具有正确的子域

should all return http://www.mydomain.com or with correct sub domain

推荐答案

您应该可以

http_build_url($parse)

注意: http_build_url 仅可通过安装pecl_http获得.

NOTE: http_build_url is only available by installing pecl_http.

根据文档，它是专门为处理parse_url的输出而设计的.这两个函数都处理锚点，查询参数等，因此没有"$ url上未提及的其他属性".

According to the docs it's designed specifically to handle the output from parse_url. Both functions handle anchors, query params, etc so there are no "other properties not mentioned on the $url".

要在缺少http://时添加http://，请在解析前使用基本检查:

To add http:// when it's missing, use a basic check before parsing it:

if (strpos($url, "http://") != 0)
    $url = "http://$url";
