Best way to remove trailing slashes in URLs with PHP
提问by daniel
I have some URLs, like www.amazon.com/, www.digg.comor www.microsoft.com/and I want to remove the trailing slash, if it exists, so not just the last character. Is there a trimor rtrimfor this?
我有一些 URL，例如www.amazon.com/, www.digg.comorwww.microsoft.com/并且我想删除尾部斜杠（如果存在），所以不仅仅是最后一个字符。是否有一个trim或rtrim这个？

You put rtrimin your answer, why not just look it up?
你rtrim输入你的答案，为什么不查一下呢？
$url = rtrim($url,"/");
As a side note, look up any PHP function by doing the following:
作为旁注，通过执行以下操作查找任何 PHP 函数：

I came here looking for a way to remove trailing slash and redirect the browser, I have come up with an answer that I would like to share for anyone coming after me:
我来这里是为了寻找一种删除尾部斜杠和重定向浏览器的方法，我想出了一个答案，我想与任何追随我的人分享：
//remove trailing slash from uri
if( ($_SERVER['REQUEST_URI'] != "/") and preg_match('{/$}',$_SERVER['REQUEST_URI']) ) {
header ('Location: '.preg_replace('{/$}', '', $_SERVER['REQUEST_URI']));
exit();
}
The ($_SERVER['REQUEST_URI'] != "/")will avoid host URI e.g www.amazon.com/ because web browsers always send a trailing slash after a domain name, and preg_match('{/$}',$_SERVER['REQUEST_URI'])will match all other URI with trailing slash as last character. Then preg_replace('{/$}', '', $_SERVER['REQUEST_URI'])will remove the slash and hand over to header()to redirect. The exit()function is important to stop any further code execution.
该($_SERVER['REQUEST_URI'] != "/")会避免主机URI如www.amazon.com/因为Web浏览器总是一个域名后发送斜线，并preg_match('{/$}',$_SERVER['REQUEST_URI'])会匹配所有其它的URI以斜线作为最后一个字符。然后preg_replace('{/$}', '', $_SERVER['REQUEST_URI'])将删除斜杠并移交header()给重定向。该exit()函数对于停止任何进一步的代码执行很重要。

$urls="www.amazon.com/ www.digg.com/ www.microsoft.com/";
echo preg_replace("/\b\//","",$urls);
