Then create the file as follows, the first step is to connect to the database, then write, and then read.
Copy the code The code is as follows:
$mysql_server_name = "localhost";
$mysql_username = "root";
$mysql_password = "";
$mysql_database = "db";
//Grab ip
$ip = getenv ("REMOTE_ADDR");
//Create a connection - through (server location, user name, user password )
$conn = mysql_connect($mysql_server_name,$mysql_username,$mysql_password);
//Get ready sql syntax This syntax is new information
$sql = "INSERT INTO `num` (`name`,`ip`, ` new` ) VALUES ('badwolf','$ip','1');";
//Select the database you want to process
mysql_select_db($mysql_database,$conn);
//Perform query
$result = mysql_query($sql);
//Result and release the connection
mysql_close($conn);
//-------------------------------- ------------------------------------------
//The following are printed information
//Establish a connection through (server location, user name, user password)
$conn = mysql_connect($mysql_server_name,$mysql_username,$mysql_password);
//Get ready for sql syntax This syntax is for reading data
$sql = "SELECT COUNT(*) FROM `num` WHERE name='badwolf' ";
//Perform query
$result = mysql_db_query($mysql_database,$sql,$conn);
//Convert the query results Fetch
$row = mysql_fetch_row($result);
//Print out all fields of the data
//print_r($row);
//Clear the results after query
mysql_free_result($result);
?> ;
