echo "1111";
//mysql_connect("127.0.0.1","root","admin");
echo "12221";
?>
当添加mysql_content(),就显示错误，tomcat中的错误日志提示：PHP Warning: PHP Startup: in Unknown on line 0
php.ini中extension=php_mysql.dll前面分号已去
跪求解

回复讨论(解决方案)

捕获一下MYSQL错误提示看看?

应该是你php的问题！

应该是你的php配置问题吧！

应该是你php的问题！
添加数据库不就是处理php.ini中的哪一句话么？在没有连接数据库之前一切都很正常的

这个可能有帮助

php和tomcat配置已经成功了，只是数据库连接时出现问题，phpinfo()也能正确显示配置的信息

在命令行中是否可以连接mysql成功呀。

phpinfo()也能正确显示配置的信息
意思是？

我机器上没装mysql，但phpinfo也能显示“正确的信息”……那只是php本身dll的信息，先确认你的mysql没问题再研究php的

出现 PHP Startup ，多半是某个扩展出加载失败
既然你是一用mysql就报错，那就是 php_mysql 加载失败了（他还需要一个支撑库）
你需要把 php 安装目录置于操作系统的搜索路径中

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
