How to achieve single article view count in php?

PHP counts the number of visits to a single article

First add a field to record the number of visits to the data table that stores the corresponding article.

• You can add one to the number of fields each time you access it, but this will be inaccurate because it will be recorded as long as it is refreshed.
  

• In order to prevent the above situation from happening, you can record the IP address of the visitor. Repeated IP address visits will only be recorded once.
  

• However, there are problems if an IP address is only recorded once. For example, if multiple visitors on a local area network share the same IP address, the records will be inaccurate. Therefore, it is best to record one visit to an IP address once within a certain period of time. This is relatively better.
  

• However, even if the IP address is recorded, there may be malicious users who switch IPs or use ticket brushing software to increase the number of visits.

<?php
$ip = $_SERVER[&#39;REMOTE_ADDR&#39;];
//循环对比数据表中储存的IP，如果IP存在，不再记录
$query = mysql_query("select * contetns where ip = &#39;".$ip."&#39;");
if(mysql_num_rows($query) > 0){
//IP存在
}else{
//记录访问量
}
?>

Note: If you want to use files without using a database, you can directly write a script on the server to count the access log
