PHP的爆炸网址 [英] php url explode
问题描述
我想从我的网址抢我的产品。例如:
I am wanting to grab my product from my url. For example:
http://www.website.com/product-category/iphone
我想抢到iphone,这是罚款与我的code,但我有一个下拉列表来排序的产品和点击将改变网址,并添加一个查询,如:
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:
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
我目前的code是
My current code is
$r = $_SERVER['REQUEST_URI'];
$r = explode('/', $r);
$r = array_filter($r);
$r = array_merge($r, array());
$endofurl = $r[1];
echo $endofurl;
这怎么可能抢iphone节所有的时间。
How is it possible to grab the iphone section all the time.
干杯
推荐答案
您可以使用PHP的 parse_url( )
功能分割的网址给你,然后访问路径
参数,并得到它的结束:
You can use PHP's parse_url()
function to split the URL for you and then access the path
parameter and get the end of it:
$r = parse_url($url);
$endofurl = substr($r['path'], strrpos($r['path'], '/'));
这将解析URL,然后采取URL的串子,从开始的最后一个发现的 /
路径。
This will parse the URL and then take a "sub-string" of the URL starting from the last-found /
in the path.
您可以选择使用爆炸('/')
作为目前工作的道路上:
You can alternatively use explode('/')
as you're currently doing on the path:
$path = explode($r['path']);
$endofurl = $path[count($path) - 1];
更新(使用 strrchr()
,指出了@ x4rf41):结果
获得字符串的结尾,而不是 SUBSTR()
+ strrpos()
是使用更短的方法 strrchr()
:
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()
:
$endofurl = strrchr($r['path'], '/');
如果您利用 parse_url的()
的选项参数,你还可以得到的只是路径的使用 PHP_URL_PATH
像
$ R = parse_url($网址,PHP_URL_PATH);
If you take advantage of parse_url()
's option parameters, you can also get just the path by using PHP_URL_PATH
like
$r = parse_url($url, PHP_URL_PATH);
或者,最短的方法:
$endofurl = strrchr(parse_url($url, PHP_URL_PATH), '/');
