打造计数器DIY三步曲(上)
人大多都很向往使用数据库来做自己的计数器,留言本,论坛之类的东西了,本篇将介绍本人自制的计数器程序。
首先建立0~9这10个GIF数字图片,放在img文件夹下,再建立一个PHP文件
——count1.php,程序如下:
$linkptr=mysql_pconnect("localhost","yourname","password");
mysql_select_db("yourname",$linkptr);
mysql_query("update counter
set visited=visited+1 where num=1",$linkptr);
$result=mysql_query("select visited
from counter where num=1",$linkptr);
list($counter)=mysql_fetch_row($result);
$counter=sprintf("%05d",$counter);
for($i=0;$i $tmpstr="";
echo $tmpstr;
}
?>
在主页上适当位置放置代码 include "count1.php" ?>,这样主页上就显示了你的计数器,不过要记住在你的数据库上建立一个TABLE——counter:create table counter(
num int unsigned,
visited int unsigned
);
怎么样,容易吧!中篇我将介绍怎样让你的镜像站也能用上你自己的计数器。

The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

Using the database callback function in Golang can achieve: executing custom code after the specified database operation is completed. Add custom behavior through separate functions without writing additional code. Callback functions are available for insert, update, delete, and query operations. You must use the sql.Exec, sql.QueryRow, or sql.Query function to use the callback function.

JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.

Through the Go standard library database/sql package, you can connect to remote databases such as MySQL, PostgreSQL or SQLite: create a connection string containing database connection information. Use the sql.Open() function to open a database connection. Perform database operations such as SQL queries and insert operations. Use defer to close the database connection to release resources.
