Garbled code problem when using echo js code on php page

When using php as a control script for the front page of html, it is often necessary to display something in the foreground. For example, use echo output. Recently, there is such a requirement on the project, and I used it echo "<script></script>" Such code, debug completely normal in the local, but 1 deployed to the server, js output to the foreground on the display of garbled code. Looking for 1 from the Internet, some people say that it can be set <script type="charset:utf-8;"></script> But after this setting, it is found that the problem still exists. Analysis, the reason why garbled code exists is that the page code is not 1 with the browser display code, or that the front-end html page is not 1 with the background control page code. So, first set the php encoding, use the header function, header("Content-type:text/html;charset:utf-8") . Then refresh the browser and display it normally. Description should be php code and browser parsing page code is not 1.
