急,火急,PHP连接数据库失败
我下载了一个开源的文件,把数据库文件导入后,怎么连接不到数据库啊
'Connect failed: Access denied for user 'root'@'localhost'
------解决方案--------------------
你得找下源码,修改连接数据库的密码。
------解决方案--------------------
检查用户名或密码是否写错。且用户名有权限。。
------解决方案--------------------
<br />//servername [服务器名] :"127.0.0.1:3306"<br />//sqlname [mysql用户名] :"ncmail"<br />//sqlpassword[mysql用户密码]:"ncmail"<br />//database [mysql数据库] :"ncmail"<br />$connect = mysql_connect("127.0.0.1:3306","ncmail","ncmail");<br /> if (!$connect){<br /> die("服务器连接失败:".mysql_error());<br /> }<br /> $conn = mysql_select_db("ncmail",$connect) or die("数据库连接失败!<br/>");<br /> mysql_query("set names utf8");<br />
------解决方案--------------------
你看你装mysql是的用户名跟密码是什么,然后改成你的用户名跟密码就ok了。
------解决方案--------------------
用户名权限不对。
简单的说,就是你的mysql账户不对。
------解决方案--------------------
账号、密码不匹配

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.

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.
