PHP如何判断INSERT是否插入成功？
具体问题：
在PHP中，用mysql_query执行一个INSERT语句后，在MYSQL控制台可查到查询成功，可是该怎么用代码判断这个语句是否执行成功？
在百度里查的这个函数返回值就是TRUE或者FALSE，但是我这边执行不管对错都是返回0呢？
解决办法：
使用PDO。
insert完成后调用$db->lastInsertid();查询最后一次插入返回的id。或者查看affected_rows

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AMDependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP Performance: Identifying and Fixing BottlenecksMay 11, 2025 am 12:13 AMPHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
