Obviously the string has been escaped. You said that this problem occurred after changing the server. It is recommended to check the web server configuration to see if automatic escaping is turned on

The person above is right, automatic escaping should be turned on. If it is inconvenient to change the configuration, you can use the stripslashes method to output.
