php url explode
提问by user1616846
I am wanting to grab my product from my url. For example:
我想从我的网址中获取我的产品。例如：
http://www.website.com/product-category/iphone
I am wanting to grab the iphone and that is fine with my code but I have a dropdown to sort products and which clicked will change the url and add a query like:
我想抓住 iphone，这对我的代码很好，但我有一个下拉菜单来对产品进行排序，点击哪个将更改 url 并添加如下查询：
http://www.website.com/product-category/iphone?orderby=popularity
http://www.website.com/product-category/iphone?orderby=new
http://www.website.com/product-category/iphone?orderby=price
http://www.website.com/product-category/iphone?orderby=price-desc
My current code is
我目前的代码是
$r = $_SERVER['REQUEST_URI'];
$r = explode('/', $r);
$r = array_filter($r);
$r = array_merge($r, array());
$endofurl = $r[1];
echo $endofurl;
How is it possible to grab the iphone section all the time.
怎么可能一直抢iphone版块。
Cheers
干杯

You can use PHP's parse_url()function to split the URL for you and then access the pathparameter and get the end of it:
您可以使用PHP的parse_url()函数为您拆分URL，然后访问path参数并获得它的结尾：
$r = parse_url($url);
$endofurl = substr($r['path'], strrpos($r['path'], '/'));
This will parse the URL and then take a "sub-string" of the URL starting from the last-found /in the path.
这将解析 URL，然后从/路径中最后找到的开始获取 URL 的“子字符串” 。
You can alternatively use explode('/')as you're currently doing on the path:
您也可以explode('/')像当前在路径上一样使用：
$path = explode($r['path']);
$endofurl = $path[count($path) - 1];
UPDATE(using strrchr(), pointed out by @x4rf41):
A shorter method of obtaining the end of the string, opposed to substr()+ strrpos()is to use strrchr():
更新（使用strrchr()，@x4rf41 指出）：
与substr()+相对的一种更短的获取字符串结尾的方法strrpos()是使用strrchr()：
$endofurl = strrchr($r['path'], '/');
If you take advantage of parse_url()'s option parameters, you can also get just the pathby using PHP_URL_PATHlike
$r = parse_url($url, PHP_URL_PATH);
如果您利用parse_url()的选项参数，您还可以通过使用like $r = parse_url($url, PHP_URL_PATH);来获取路径PHP_URL_PATH。
Or, the shortest method:
或者，最短的方法：
$endofurl = strrchr(parse_url($url, PHP_URL_PATH), '/');

If you want to retrieve the last element of the array, you can use the endfunction. The rest of your code seems to be working.
如果要检索数组的最后一个元素，可以使用end函数。您的其余代码似乎正在运行。
$endofurl = end($r);
You could also leverage parse_urland strrchrfunctions to make it more concise:
您还可以利用parse_url和strrchr函数使其更简洁：
$endofurl = strrchr(parse_url($url, PHP_URL_PATH), '/');

Just figured it out.This now works with
刚刚想通了。现在可以使用
$r = $_SERVER['REQUEST_URI'];
$r = explode('/', $r);
$r = array_filter($r);
$r = array_merge($r, array());
$r = preg_replace('/\?.*/', '', $r);
$endofurl = $r[1];
echo $endofurl;
