Three steps to build a counter DIY

In the middle part, I introduced you how to place the counter on OSO on your own mirror site. In this article, I will introduce you to the idea of ​​how to build your own free counter system. You have to write the program yourself.
Many websites provide it With the free counter service, I had a dream a long time ago to build my own free counter system, and now OSO provides the database, all this will become a reality.
Most websites only provide free counters to members, we can do the same Do it so that your website can also have some subjects. When they register, an ID can be automatically generated. Our counter system relies entirely on this ID!
When a user applies for a counter, the first step is to check the user name and password. After successful login, the user's ID is retrieved from the database. After the user applies, the system automatically creates two files, countid.php and showid.php. A simple process can be As follows:
$filea="count".$id."php";
$fileb="show".$id."php";
$fpa=fopen("count/$filea",w);
$ fpb=fopen("show/$fileb",w)
Then write the file. The content is similar to that in the medium. Just change the num. The simple process can be as follows:
fputs($fpa,$count, strlen($count));
fputs($fpb,$show,strlen($show));
The content in $count=countid.php;
The content in $show=showid.php;
This is how it is generated For the two files countid.php and showid.php, just let the database insert num=id at the same time, and finally return a piece of code to let the user know how to use this counter, and everything is done!
But I think the user can set the initial value when applying for the counter. When inserting num into the database, use replace instead of insert. In this way, if the user forgets the code, he can reapply for one at any time and set the initial value, and the counter will replace the original record. By covering it, there is no need for users to remember the code or provide code returns, which is too troublesome!
How is it? Everything is very easy. I hope you can successfully create your own counter system through these three articles. I wish you success!

The above has introduced the three-step process of building a counter DIY, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
