Your PHP part is wrong

Set your IE to turn the error display mode on. You'll know what's going on when you open a PHP error message.

Thank you phpnewnew, I am the error dialog box that pops up when I connect to MySQL in Dreamweaver, it is not related to the display in IE, and the wrong display mode of IE is open. This is actually the problem: http://zhidao.baidu.com/question/315250344.html, but his answer did not solve my problem, strong solution.

------Solution--------------------
1, in the php.ini order
Display_errors = On

2. If your database connection code is not written by you, it is created by Dreamweaver
Please make sure MySQL is up
The database name, user name, and password you provided are incorrect

The HTTP 500 error means: The server refuses to respond
For PHP applications, the most likely occurrence of this error is that PHP detects a problem with the program and cannot output an error (Display_errors = Off)

Of course there may be other reasons, but the problem is always a step-by-step troubleshooting
