There are four ways to achieve pseudo-static in PHP, do you think of them? , No. 4 Middle School

Speaking of the pseudo-static implementation plan, are you very happy to answer "It's simple, just configure the rewrite rules of apache and that's it"

But have you noticed this situation? You have recently developed a lot of new features. Several new features are added every day, and there are many pseudo-static configurations every day. It has only been two days since the operation and maintenance, and the classmates are willing to cooperate. After two days, the operation and maintenance Classmate Wei was about to scold him. Why don't you do it all at once and bother me every day because you are so numb and stupid? But, you are about to go online, and you have to ask the operation and maintenance classmates hard, and then say the most shameless words in the programmer world: "This is the last change", and then you have to change it again. , Sigh, your personality is completely ruined. . .

If you have such troubles, please read the following article to ensure that you will never ask for operation and maintenance again in the future, and you can do whatever you want. . .

So how many ways are there to implement pseudo-static in PHP? Personal opinions and statistics, there are four methods

1. Use apache’s URL rewriting rules. Everyone knows this. Configure it in apache. Here, students all made it. I only list a simple configuration

<span>RewriteEngine On
RewriteRule </span>^/test.html index.php?controller=index&action=test [L]

Copy after login

2. Use PHP's pathinfo. Have you seen some websites playing 'www.xxx.com/index.php/c/index/a/test/id/100' like this? Of course, this must be supported. You need to put the parameters in 'php.ini'

'cgi.fix_pathinfo' is set to 1. Take 'www.xxx.com/index.php/c/index/a/test/id/100' as an example

<span>echo</span> <span>$_SERVER</span>['PATH_INFO']; <span>//</span><span>输出'/c/index/a/test/id/100'</span>

Copy after login

At this point, you should understand it. You can then parse this paragraph and assign the actual address

3. Use the 404 mechanism. Generally, pseudo-static pages are pages that do not actually exist, so you can use apache 404 configuration. However, there are some problems. 'post' type requests will be abandoned, causing you to be unable to obtain '$ _POST',

But '$_GET' can still be obtained. Assume that the 404 page here is '404page.php', and the apache configuration is as follows:

ErrorDocument 404 /404page.php

Copy after login

Then embed the following code in '404page.php'

<span>header</span>("HTTP/1.1 200 OK"); <span>//</span><span>这里一定要有，不然状态就是404</span>

<span>$reqUrl</span> = <span>$_SERVER</span>['REQUEST_URI']; <span>//</span><span> 请求地址</span>

<span>/*</span><span>*
* 从URL中解析参数
</span><span>*/</span>
<span>function</span> parseUrlParams(<span>$queryUrl</span><span>)
{
    </span><span>$arr</span> = <span>explode</span>('?', <span>$queryUrl</span><span>);
    </span><span>parse_str</span>(<span>$arr</span>[1], <span>$param</span><span>);
    </span><span>if</span>(<span>$param</span><span>)
    {
        </span><span>foreach</span>(<span>$param</span> <span>as</span> <span>$key</span> => <span>$value</span><span>)
        {
            </span><span>$_GET</span>[<span>$key</span>] = <span>$value</span><span>;
        }
    }
}

parseUrlParams(</span><span>$reqUrl</span>); <span>//</span><span> url解析参数

//然后你就可以使用 $reqUrl 根据自己的规则匹配不同的实际请求地址</span>
<span>if</span>(<span>preg_match</span>('#^/test.html#is', <span>$reqUrl</span>, <span>$matches</span><span>))
{
   </span><span>include</span>('index.php'<span>);
   </span><span>die</span><span>();
}</span>

Copy after login

4. An improved version of method 3. Method 3 is equivalent to redirection in the internal mechanism of apache, causing the parameters passed by post(get) to be unobtainable. Analysis of the above actually shows that the relevant files cannot be found. When the server cannot find the relevant files, we specify a file for it. If it is OK, it will not need to jump. At this time, POST and the like will not be lost. The apache configuration is as follows:

<span>RewriteEngine On
RewriteCond </span>%{REQUEST_FILENAME} !-<span>f
RewriteCond </span>%{REQUEST_FILENAME} !-<span>d
RewriteRule </span>. index.php

Copy after login

The general meaning of the above configuration is that when the requested file or directory cannot be found, use 'index.php' in the root directory instead. Then you can get the relevant parameters in 'index.php' and parse to Actual request address

<span>/*</span><span>*
* 获取当前请求的URI地址
*@param void
*@author painsOnline
*@return string URI
</span><span>*/</span>
<span>function</span><span> getReqUri()
{
    </span><span>return</span> <span>trim</span>(<span>$_SERVER</span>["REQUEST_URI"<span>]);
}

</span><span>$reqUri</span> =<span> getReqUri();

</span><span>if</span>(<span>preg_match</span>('/^\/test.html/isU', <span>$reqUri</span><span>))
{</span><span>//</span><span>解析请求地址</span>
    <span>include</span> 'test.php'<span>;
    </span><span>exit</span><span>();
}</span>

I have little talent and knowledge, and I have some shortcomings. Welcome to make up for them
