Deprecation of mysql_connect(): Migration to MySQLi or PDO
You have encountered the deprecation warning for mysql_connect(). This means that the mysql extension is being phased out and will eventually be removed. To eliminate this warning and ensure continued functionality, you need to migrate your code to either the MySQLi or PDO extensions.
Solution: Using MySQLi Extension
One option is to use the MySQLi extension, which is a modern replacement for the mysql extension. The syntax is slightly different, but it offers similar functionality. Below is an example:
<?php $connection = mysqli_connect('localhost', 'username', 'password', 'database'); ?>
Query Execution with MySQLi
Query execution with MySQLi is also similar to the mysql extension:
<?php mysqli_query($connection, 'CREATE TEMPORARY TABLE `table`'); ?>
Suppressing Deprecated Warnings
Alternatively, you can suppress all deprecated warnings, including those from mysql_* functions, by using the following code:
<?php error_reporting(E_ALL ^ E_DEPRECATED); ?>
In some cases, you may need to locate the specific file and line where the warning is triggered. Once identified, you can replace error_reporting(E_All); with error_reporting(E_ALL ^ E_DEPRECATED);.

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.
