1. Operate based on $_SERVER['PATH_INFO'].
For example, the address of your website is http://127.0.0.1/show_new.php/look-id-1.shtml
The result of your echo $_SERVER['PATH_INFO'] It will be /look-id-1.shtml. After seeing this, I think everyone may have understood it.
Complete demo
index.php

Copy code The code is as follows:

index.php

$conn=mysql_connect("localhost","root","root")or dir("Connection failed");
mysql_select_db("tb_demo",$conn);
$sql="select * from news";
$res=mysql_query($sql);
header("content-type:text/html;charset=utf-8");
echo "

News list

";
echo "Add News
";
echo "";
echo "";
while($row=mysql_fetch_assoc($res)){
echo "< ;td>{$row['title']}";
}
//The red address above should have been show_news.php?act=look&id={$row['id']}
echo "
idtitleView detailsModify news
{$row['id']}View DetailsModify page
";
//Close the resource
mysql_free_result($res);
mysql_close($conn);


show_new.php page
Copy code The code is as follows :

show_new.php

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 $pa is /look-id-1 .html
//URL address obtained through regular expression matching
if(preg_match('/^/(look)-(id)-([d]).shtml$/',$pa,$ 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 $res['title']."< ;hr>".$res['content'];
}else{
echo "url address is illegal";
}
mysql_close($conn);


After seeing the above, I think everyone must understand it. In fact, this method is not used much, so I will tell you the second method below

2. Implement according to 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- as the encoding. After 8 is encoded, you will see this .htaccess file in the directory

First, open mod_rewrite.so in apache, AllowOverride None. There are two places here that are replaced with AllowOverride All

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

Copy code The code is as follows:


#Write your rewrite rules
RewriteEngine On
# Multiple rules can be configured, and the matching order is from above Go to the next
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


You will definitely echo $_GET['id'] on the one_new.php page Output the value of id

Note: Currently my personal ability can only be written here. I will gradually improve it in the future
