When to Abandon the mysql_* Functions in PHP
If you're still utilizing mysql_* functions like mysql_query() or mysql_connect(), it's time to reconsider. Here's why:
Reasons to Avoid mysql_* Functions
- Deprecation: mysql_* functions are officially deprecated as of PHP 5.5 and have been completely removed in PHP 7.0. This means that their use compromises your code's future compatibility and security.
- Lack of OO Interface: mysql_* functions lack an object-oriented interface, making them less convenient and efficient compared to more modern extensions.
- Limited Functionality: mysql_* functions don't support essential features such as prepared statements, multiple statements, and transactions. They also lack support for newer MySQL capabilities introduced since MySQL 5.1.
Errors and Workarounds
If mysql_* functions are no longer available on your site, you may encounter "No such file or directory" errors. To resolve this, you should:
- Upgrade to PHP Version 7.0 or Later: This will automatically discard mysql_* functions and prompt you to adopt alternative PHP extensions.
- Use mysqli or PDO Extensions: These modern extensions offer more advanced functionality and better compatibility with the latest MySQL versions.
Benefits of Modern PHP Extensions
By switching to mysqli or PDO extensions, you gain access to:
- Prepared statements for enhanced data security and efficiency
- Support for advanced database features and procedures
- Simplified syntax and improved user experience
- Superior performance and scalability

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.
