Parsing URL query in PHP
提问by Maelish
Assuming a url of www.domain.org?x=1&y=2&z=3, what would be a smart method to separate out the query elements of a url in php without using GET or REQUEST?
假设一个 url www.domain.org?x=1&y=2&z=3，在不使用 GET 或 REQUEST 的情况下，在 php 中分离出 url 的查询元素的智能方法是什么？
$url = parse_url($url);
echo $url[fragment];
I don't think it's possible to return query parts separately is it? From what I can tell the query will just say x=1&y=2&z=3but please let me know if I am wrong. Otherwise, what would you do to parse the $url[query]?
我认为不可能单独返回查询部分是吗？据我所知，查询只会说，x=1&y=2&z=3但如果我错了，请告诉我。否则，你会怎么做来解析$url[query]？
Edit: Fragment should be Query instead. Sorry for the confusion, I am learning!
编辑：片段应该是查询。抱歉打扰了，学习了！

You can take the second step and parse the query string using parse_str.
您可以执行第二步并使用parse_str解析查询字符串。
$url = 'www.domain.org?x=1&y=2&z=3';
$url_parts = parse_url($url);
parse_str($url_parts['query'], $query_parts);
var_dump($query_parts);
I assumed you meant the query string instead of the fragment because there isn't a standard pattern for fragments.
我假设您指的是查询字符串而不是片段，因为片段没有标准模式。

parse_urlfunction returns several components including query. To parse it you should run parse_str.
parse_url函数返回几个组件，包括query. 要解析它，您应该运行parse_str.
$parsedUrl = parse_url($url);
parse_str($parsedUrl['query'], $parsedQueryString);
If you are going just to parse your HTTP request URL:
如果您只想解析您的 HTTP 请求 URL：
use
$_REQUEST['x'],$_REQUEST['y'],$_REQUEST['z']variables to access x,y,z parameters;use
$_SERVER['QUERY_STRING']to get whole URL querystring.
使用
$_REQUEST['x'],$_REQUEST['y'],$_REQUEST['z']变量访问 x,y,z 参数；用于
$_SERVER['QUERY_STRING']获取整个 URL 查询字符串。

I was getting errors with some of the answers above but they did lead me to the right answer. Thanks guys.
我在上面的一些答案中遇到了错误，但它们确实让我找到了正确的答案。谢谢你们。
$url = 'www.domain.org?x=1&y=2&z=3';
$query = $url[query];
parse_str($query);
echo "$x &y $z";
And this outputs: 1 2 3, which is what I was trying to figure out.
这输出：1 2 3，这就是我想要弄清楚的。

As a one liner with no error checking
作为没有错误检查的单班轮
parse_str(parse_url($_SERVER['REQUEST_URI'], PHP_URL_QUERY), $query);
$querywill contain the query string parameters
unlike PHP's $_GET, this will work with query params of any length
$query将包含
与 PHP 不同的查询字符串参数$_GET，这将适用于任何长度的查询参数

I highly recommend using this url wrapper https://github.com/weew/url(which I have written)
我强烈建议使用这个 url 包装器https://github.com/weew/url（我写的）
It is capable of parsing urls of complexity like protocol://username:[email protected]:80/some/path?query=value#fragmentand has many more goodies.
它能够解析复杂的 url，比如protocol://username:[email protected]:80/some/path?query=value#fragment并且有更多的好东西。
