如何使用mod_rewrite显示SEO友好的URL? [英] How can I display SEO friendly URLs using mod_rewrite?

问题描述

我并不是一个PHP开发人员，我被要求在现有的PHP网站上执行一些SEO.

I am not a PHP developer at heart and I have been asked to perform some SEO on an existing PHP website.

我注意到的第一件事是丑陋的URL，所以我想让它们重写为更有用的信息.这是所有可能的模式:

The first thing I noticed was the ugly URLs so I want to get these to rewrite to something more informative. Here are all the possible patterns:

/index.php?m=ModuleType&categoryID=id
/index.php?m=ModuleType&categoryID=id&productID=id
/index.php?page=PageType
/index.php?page=PageType&detail=yes

所以基本上我想做的就是将它们转换为类似的东西:

So basically what I want to do is convert these into something like:

/ModuleType/Category
/ModuleType/Category/ProductName
/Page
/Page

在没有任何建议或示例之前，我还没有使用过mod_rewrite！

I haven't used mod_rewrite before any advice or examples would be great!

谢谢.

推荐答案

mod_rewrite 宁愿相反:将内部的/ModuleType/Category/ProductName请求重写为/index.php?m=ModuleType&categoryID=id&productID=id.在文档中使用新的URL是您应用程序的工作.

mod_rewrite would rather be used to do the opposite: rewrite requests of /ModuleType/Category/ProductName internally to /index.php?m=ModuleType&categoryID=id&productID=id. Using the new URLs in the documents is the job of your application.

编辑.以下是一个函数外观示例，该函数将参数化的URL转换为新的URL:

Edit    Here’s an example of how a function might look like that turns your parameterized URLs into the new ones:

function url($url, $rules) {
    $url = parse_url($url);
    parse_str($url['query'], $url['query']);
    $argNames = array_keys($url['query']);
    foreach ($rules as $rule) {
        if ($rule[0] == $url['path'] && array_keys($rule[1]) == $argNames) {
            $newUrl = $rule[2];
            foreach ($rule[1] as $name => $pattern) {
                if (!preg_match('/'.addcslashes($pattern, '/').'/', $url['query'][$name], $match)) {
                    continue 2;
                }
                $newUrl = str_replace('<'.$name.'>', $match[0], $newUrl);
            }
            return $newUrl;
        }
    }
    return $url;
}

$rules = array(
    array(
        '/index.php',
        array('m'=>'.*', 'categoryID'=>'.*', 'productID'=>'.*'),
        '/<m>/<categoryID>/<productID>'
    )
);
echo '<a href="' . url('/index.php?m=ModuleType&categoryID=categoryID&productID=productID', $rules) . '">/ModuleType/Category/ProductName</a>';
