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
