PHP5.1
LINUX系统
服务器没有安装sqlserver，只是需要去访问其他服务器的mssql数据库，
已经开启php.ini的extension=php_mssql.dll，重启apache后
还是提示Call to undefined function mssql_connect()
请问要如何处理，谢谢！
回复讨论(解决方案)
查看phpinfo函数看有没有mssql这个模块，没有的话装上
linux 不是要编译吗
贴出你代码瞧瞧呗
要看看有没有这个模块！光开启是没用的，有的模块需要下载
linux下开启扩展是没用的，还需要安装另一个组件。
不建议去访问mssql。

LINUX下的PHP有extension=php_mssql.dll吗？
extension=php_mssql.so 是这个吧
提示Call to undefined function mssql_connect() 说明你linux下没有安装支持mssql数据库服务吧，跟支持mysql一样需要安装个mysql数据库服务软件
一般是需要FreeTDS
不需要安装mysql，但是系统必须有相应的支持模块
linux 下安装
使用php -m检查一下看看有没有mssql的扩展
架构搭配错误。。。。

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.
