Database-based counters (mysql )?
1. create a database first:
Create table counter {
Counter int not null,
Id int not null
}
Insert into counter (counter, id) VALUES (0, 1)
2. COUNTER Code:
<〈?
// PHP counter, based on the MySQL database server.
Function linuxcounter (){
// Connect to the MySQL database
$ Conn = mysql_connect ("localhost", phpbook ","");
// Query the current number of views
// Note the method for obtaining the result
$ SQL = "select * from counter ";
$ Result = mysql_query ($ SQL, $ conn );
$ ObjResult = mysql_fetch_object ($ result );
$ Count = $ objResult-> counter;
// Update the database and return the current browser count as the result
$ SQL = "update counter set counter =". ($ cont + 1). "where id = 1 ";
Mysql_query ($ SQL, $ conn );
Mysql_close ($ conn );
Return $ count + 1;
}
