Three Steps to DIY a Counter (Part 2)_PHP Tutorial

In the middle article, 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 All provide free counter services. 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 also do this so that there are some subjects on our website. 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 username 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. Simple The 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 the one in the medium, just change the num, simple process It can be as follows:
fputs($fpa,$count,strlen($count));
fputs($fpb,$show,strlen($show));
$count=countid.php Content;
Contents in $show=showid.php;
This generates two files, countid.php and showid.php. At the same time, let the database insert num=id. Finally, return a piece of code to let The user knows 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 value. The records are overwritten, so there is no need for users to remember the code or provide code returns, which is too troublesome!
How about it? Everything is very easy. I hope you can successfully create your own counter system through these three articles. I wish you success!
