Google如何处理两个具有不同值的相同URL参数? [英] How does google handle two same URL parameters with different values?

问题描述

只要看看这个URL，您就会知道我的意思.

Just take a look at this url, and you will know what I mean.

https://www.google.com/search?q=site%3Aphpjs.org&q=date

当我转到该URL时，谷歌搜索栏中的搜索词是site:phpjs.org date.

And when I go to that url, the search term in google's search bar is site:phpjs.org date.

Google如何将两个参数一起变形"，如何在PHP中做到这一点?

How does Google 'morph' the two parameters together, and how would one do it in PHP?

推荐答案

Google使用相同的q变量来完成相同的操作，而不是对空间进行编码.

Instead of encoding the space, Google uses the same q variable to accomplish the same thing.

不幸的是，PHP没有内置的功能来执行此操作，因为除非使用[]后缀，否则连续出现的相同查询字符串参数将覆盖第一个参数.

Unfortunately, PHP doesn't have the built-in ability to do this, because successive occurrences of the same query string parameter will overwrite the first one, unless the [] suffix is used.

您将需要以下内容:

$params = array();
foreach (explode('&', $_SERVER['QUERY_STRING']) as $param) {
    list($name, $value) = explode('=', $param, 2);
    $params[] = array(urldecode($name) => urldecode($value));
}

$params的内容:

array(
    array('q' => 'site:phpjs.org'),
    array('q' => 'date'),
);

或者，您可以将循环体更改为此:

Alternatively, you can change the loop body to this:

$params[urldecode($name)][] = urldecode($value);

这会将$params更改为:

array('q' => array('site:phpjs.org', 'date'));

这样做会更容易:

join(' ', $params['q']);
// "site:phpjs.org date"
