可以，只需检查最后一个字符是否为斜杠，然后核对该斜杠即可.

Sure it is, simply check if the last character is a slash and then nuke that one.

if(substr($string, -1) == '/') {
    $string = substr($string, 0, -1);
}

另一种(可能更好)的选择是使用rtrim()-此选项将删除所有尾部斜杠:

Another (probably better) option would be using rtrim() - this one removes all trailing slashes:

$string = rtrim($string, '/');
