//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

//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);

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
