情况是这样的
做了两个动态库，一个是操作sqlite的，一个是操作postgresql的。这两个动态库接口是一样的。
再做一个PHP扩展模块，调用sqlite的动态库或者postgresql的动态库。
Windows下都正常，在链接的时候会找对应的lib，调用sqlite或者postgresql都行。
但Linux下，编译PHP扩展模块的时候，只找头文件，不找动态库。编译是通过了，但运行的时候就出错。怎么解决下。

回复讨论(解决方案)

先ldd看一下你的扩展是否有找到动态库。
如果可以在加一下ld.so.conf中的动态库搜索路径

找到方法了，
修改 config.m4
PHP_ADD_LIBRARY_WITH_PATH(dbsl, /lib64, ASSETSCTL_SHARED_LIBADD)

先ldd看一下你的扩展是否有找到动态库。
如果可以在加一下ld.so.conf中的动态库搜索路径
请问是如何修改的？我也碰到这也的错误！

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency 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 AM

PHP 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.
