The use of pseudo-static in PHP is mainly to hide the passed parameter names. Speaking of the implementation of pseudo-static, do you readily answer "Simple, configure the rewrite of apache" Just follow the rules."

But have you ever noticed this situation? You have recently developed a lot of new features. Several new features are added every day. There are many pseudo-static configurations every day. It has only been two days. The operation and maintenance students are still willing to cooperate, but in two days the operation and maintenance students will scold me. 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 later, hey, your personality It's a clean sweep. . .

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. . .

How many ways are there to implement pseudo-static in PHP? Personal opinion and statistics, there are four methods

1. Use apache’s URL rewriting rules. Everyone knows this. Configure it in apache. Here, students have all created it. I will only list a simple one. Configuration

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

2. Use PHP's pathinfo, you Have you ever seen some websites playing with 'www.xxx.com/index.php/c/index/a/test/id/100' like this? Of course, to support this, you need to change 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

echo $_SERVER['PATH_INFO']; //Output'/c /index/a/test/id/100'
You should understand this, you can parse this paragraph and assign the actual address

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

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

ErrorDocument 404 /404page.php

Then in ' The following code is embedded in 404page.php'

header("HTTP/1.1 200 OK"); //这里一定要有,不然状态就是404
$reqUrl = $_SERVER['REQUEST_URI']; // 请求地址
/**
* 从URL中解析参数
*/
function parseUrlParams($queryUrl)
{
$arr = explode('?', $queryUrl);
parse_str($arr[1], $param);
if($param)
{
foreach($param as $key => $value)
{
$_GET[$key] = $value;
}
}
}
parseUrlParams($reqUrl); // 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
if(preg_match('#^/test.html#is', $reqUrl, $matches))
{
include('index.php');
die();
}

4. An improved version of method 3. Method 3 is equivalent to redirection in the internal mechanism of apache, resulting in the inability to obtain the parameters passed by post(get). 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:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php

Above The general meaning of a 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 the actual request address

/**
* 获取当前请求的URI地址
*@param void
*@author painsOnline
*@return string URI
*/
function getReqUri()
{
return trim($_SERVER["REQUEST_URI"]);
}
$reqUri = getReqUri();
if(preg_match('/^\/test.html/isU', $reqUri))
{//解析请求地址
include 'test.php';
exit();
}
rrree
