比如商品上架12点,到明天的12点下架,然后有很多商品,分别有各自的上下架时间,难道每次查询的时候都判断是否在时间段内?这样会很慢的吧?每次都判断每个商品会影响效率的吧?

回复内容：

一般已经下架的商品在搜索的时候，是被排除在外的。除非你是之前收藏了这个商品的链接了，然后自己又重新打开了这个链接，这个时候后台查询到当前商品已经下架，就在界面上显示一下已下架。所以说是每次查询的时候判断的，但是被查询到的概率很小。

Best PHP Performance Optimization TechniquesMay 07, 2025 pm 03:05 PM

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.

PHP Dependency Injection: Boost Code MaintainabilityMay 07, 2025 pm 02:37 PM

Dependency injection provides object dependencies through external injection in PHP, improving the maintainability and flexibility of the code. Its implementation methods include: 1. Constructor injection, 2. Set value injection, 3. Interface injection. Using dependency injection can decouple, improve testability and flexibility, but attention should be paid to the possibility of increasing complexity and performance overhead.

How to Implement Dependency Injection in PHPMay 07, 2025 pm 02:33 PM

Implementing dependency injection (DI) in PHP can be done by manual injection or using DI containers. 1) Manual injection passes dependencies through constructors, such as the UserService class injecting Logger. 2) Use DI containers to automatically manage dependencies, such as the Container class to manage Logger and UserService. Implementing DI can improve code flexibility and testability, but you need to pay attention to traps such as overinjection and service locator anti-mode.
