PHP:构建URL路径

Question

我有几个字符串组合起来构建一个完整的路径.例如

$base = "http://foo.com";
$subfolder = "product/data";
$filename = "foo.xml";

// How to do this?
$url = append_url_parts($base, $subfolder, $filename); ???

字符串连接不会,这将省略必要的正斜杠.

在Win32中,我使用PathCombine()或PathAppend(),它将处理在字符串之间添加任何必要的斜杠,而不会加倍.在PHP中,我应该使用什么？

尝试这个：

$base = "http://foo.com";
$subfolder = "product/data";
$filename = "foo.xml";

function stripTrailingSlash(&$component) {
    $component = rtrim($component, '/');
}
$array = array($base, $subfolder, $filename);
array_walk_recursive($array, 'stripTrailingSlash'); 
$url = implode('/', $array);
