Question

我从PHP: Good solution for MVC routing function to parse requested views?获取了建议的解决方案，并将其添加到我们的内部指南中（再次感谢Supericy）。

我现在有以下代码：

public function parseRequestedView($url) {

    $this->view_requested = explode('/', trim($url, '/'));

    // Format: [0] viewpoint, [1] child, [2] action (default: show), [3] reference
    $this->view_map = array(
        $this->parseViewMapArrayKey('device/:reference:/configurations') => array(0,  2, -1,  1),
        $this->parseViewMapArrayKey('device/:reference:')                => array(0, -1, -1,  1)
    );

    foreach ($this->view_map as $this->view_map_transitory => $this->view_map_indices) {

        if (preg_match($this->view_map_transitory, $url)) {

            foreach ($this->view_map_indices as $this->view_index) {

                $this->view_resources[] = $this->view_index > -1 ? $this->view_requested[$this->view_index] : null;

            }

            return $this->view_resources;

        }

    }

    return false;

}

public function parseViewMapArrayKey($key) {

    return '#'.str_replace([":reference:", ":string:"], ["\d+", ".+"], $key).'#';

}

它工作正常，除了一个小问题＆＃34;：

当我切换键＆＃34;设备/：参考：＆＃34;和＆＃34;设备/：参考：/配置＆＃34;然后调用device /：reference：/ configurations的视图，我只得到device /：reference的结果。

例如，http://ww.foo.com/device/123456/configurations将输出：

Array
(
    [0] => device
    [1] => 
    [2] => 
    [3] => 123456
)

http://ww.foo.com/device/123456的结果是什么。当我将密钥更改回原始顺序时，一切都应该是：

Array
(
    [0] => device
    [1] => configurations
    [2] => 
    [3] => 123456
)

当我切换按键时，如何反转搜索顺序或使功能输出正确的结果？

我发现了PHP Reverse Preg_match。但据我所知，这是一个负面的preg_match。或者我错了？

提前致谢。

好吧也许这是一个愚蠢的答案，但也许你可以确保你的正则表达式以^开头并以$结尾？

例如

public function parseViewMapArrayKey($key) {

    return '#^'.str_replace([":reference:", ":string:"], ["\d+", ".+"], $key).'$#';

}

PHP：调用preg_match的搜索顺序的解决方案
