echo "
";
}
//The red address above It should have been show_news.php?act=look&id={$row['id']}
echo "

id title View details Modify news

{$row['id']} { $row['title']} View details Modify page

";
//Close the resource
mysql_free_result($res);
mysql_close($conn);
?>

Copy code

2, show_new.php page

header("Content-type:text/html;charset=utf-8");
$conn=mysql_connect("localhost","root","root");
mysql_select_db("tb_demo",$conn);
mysql_query("set names utf8");
$pa = $_SERVER['PATH_INFO'];
//The printed value of $pa is /look-id-1.html
//The url address obtained through regular expression matching
if(preg_match('/^/(look)-(id)-([d]).shtml$/',$pa,$arr)){
$ act = $arr[1]; //This is the requested look method
$id = $arr[3]; //This is the obtained id value
$sql="select * from news where id= $id";
$res=mysql_query($sql);
$res = mysql_fetch_assoc($res);
echo $res['title']."
".$res['content'];
}else{
echo "url address is illegal";
}
mysql_close($conn);
?>

Copy the code

Second, implement it according to the configuration .htaccess Let’s first talk about how to create the .htaccess file. Create a notepad in the root directory of the website and then double-click to open it. Click Save as and write the file name as .htaccess. Select all files as the save type and utf-8 as the encoding. This is what you need. I saw this .htaccess file in the directory.

First, open mod_rewrite.so in apache, and replace AllowOverride None in two places with AllowOverride All.

For example, the href address is written as one_new-id-1.shtml //This means one_new.php?id=1 The .htaccess here is written like this:

#Write your rewrite rules
RewriteEngine On
# You can configure multiple rules, and the matching order is from top to bottom
RewriteRule one_new-id-(d+).shtml$ one_new .php?id=$1 //$1 here represents the first parameter
RewriteRule abc_id(d+).html$ error.php
#Set 404 error
#ErrorDocument 404 /error.php

Copy the code

In one_new.php page echo $_GET['id'] will definitely output the value of id.

Let’s just introduce these. It is very simple to implement pseudo-static in PHP. I hope you can practice more and write more flexible and lightweight pseudo-static rules.
