    我也写一个
    <?php
    class Route{
    public static $rules = [];

    public static function addRule($uri,$rule,$defaults=[])
    {
    //$rule_param = [];
    self::$rules[] = ['regex'=> self::compileRule($uri,$rule) , 'defaults'=>$defaults ];
    }
    public static function compileRule($uri,$rule)
    {
    $uri = str_replace(')', ')?', $uri);
    return preg_replace_callback(
    "#<([^<>/\?]+)>#i",
    function ($matches) use ($rule){
    $name = $matches[1];
    return "(?P<{$name}>" . ( !empty($rule[$name]) ? $rule[$name] : '[^<>/]+') . ')';
    },
    $uri
    );

    }
    public static function parseUri($uri){
    foreach (self::$rules as $rule_setting) {
    if ( preg_match("#{$rule_setting['regex']}#i", $uri, $matches) ){
    $ret = $rule_setting['defaults'];
    foreach ($matches as $name => $value) {
    $ret[$name] = $value;
    }
    return $ret;
    }
    }
    return NULL;
    }
    }
    //example
    Route::addRule(
    '<controller>/<action>(/<param>)',
    ['controller'=>'[a-z]+','action'=>'[a-z]+'],
    ['controller'=>'home','action'=>'index']
    );
    Route::addRule(
    'a_<param>.html',
    ['param'=>'[0-9]+'],
    ['controller'=>'article','action'=>'detail']
    );
    print_r(Route::parseUri('a_1234.html'));
    print_r(Route::parseUri('find/me'));
    print_r(Route::parseUri('find/somebody/tom'));

    If you need more than 3 levels of indentation, you’re screwed anyway, and should fix your program.

    推荐一个精简的 Router 库做路由控制器 https://github.com/lloydzhou/router ,可以根据映射的 handler 自动从 request 获取变量,支持自定义 error handler 和 hook 。可以通过 hook 方便的定制参数过滤、登录检查等。

    (new Router())
    ->error(405, function($message){
    header('Location: /hello/world', true, 302);
    })
    ->get('/hello/:name', function($name){
    echo "Hello $name !!!";
    })
    ->execute();
