How to Balance Performance and Maintainability: Calculating in MySQL vs. PHP?

性能与可维护性:在 MySQL 与 PHP 中平衡计算

在数据库中经常出现在 MySQL 与 PHP 中执行计算之间的争论 -以应用程序为中心。虽然有些人主张通过将所有计算外包给 MySQL 来保持代码结构的简单性,但其他人则优先考虑速度和效率。要确定最佳方法,必须同时考虑性能和可维护性。

在 MySQL 中执行计算的优点:

  • 针对数据管理进行优化:MySQL 是专门为存储和操作数据而设计的,使其能够更高效地进行涉及多行和多列的复杂计算。
  • 最大限度地减少数据传输:在 MySQL 中执行计算可减少数据传输量需要在数据库和 Web 服务器之间传输的数据,可能会提高性能。

PHP 计算的好处:

  • 增强的功能:PHP 提供了操作字符串、解析日期和执行复杂逻辑操作的强大功能,这在 MySQL 中可能具有挑战性。
  • 改进的可维护性:将计算保持在内部PHP 允许更轻松的代码可读性、调试和版本控制,减少出现错误的可能性并简化维护。

平衡注意事项:

实现平衡在性能和可维护性之间,建议:

  • 优先考虑 MySQL 的数据库任务: 利用 MySQL 来执行利用其优化功能的任务,例如过滤、排序和聚合数据。
  • 将字符串和日期操作卸载到 PHP: 由于 PHP 的增强功能,可以在 PHP 中处理复杂的字符串和基于日期的计算。
  • 考虑 DB和 Web 服务器时区:如果使用日期计算,请通过在数据库或 PHP 中生成日期来确保日期格式的一致性,以避免潜在的时区差异。

具体示例分析:

  • Selecting Users Created in the Last 24 Hours: While it's possible to achieve this using a NOW() - 1 day calculation in MySQL, it might be more efficient to perform the calculation in PHP to accommodate timezone considerations.
  • Capitalizing First and Last Names: This task is best handled in PHP due to its superior string manipulation capabilities, allowing for consistent handling of special cases like titles and middle initials.
  • String Concatenation: If strings will be used independently, it might be more performant to retrieve them separately and concatenate them in PHP when needed. However, for large datasets, performing the concatenation in MySQL can reduce the amount of data transferred.

Conclusion:

The choice between performing calculations in MySQL or PHP depends on the specific requirements of the application. By considering the advantages and limitations of each approach, developers can strike a balance between performance and maintainability, ensuring an efficient and maintainable database-driven system.

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
