Description:

The header() function is used to send the information in the brackets to the http header.

If the content in the brackets is as mentioned in the article, the function is basically the same as the label. If you compare the first one, you will find that the characters are similar. But the difference is that if there is this function, the browser will always use the xxx encoding you requested and will never be disobedient, so this function is very useful.

Why is this so? Then we have to talk about the difference between HTTPS headers and HTML information:

The https header is a string sent by the server before transmitting HTML information to the browser using the HTTP protocol.

Because the meta tag belongs to html information, the content sent by header() reaches the browser first. The popular point is that header() has a higher priority than meta (I don’t know if this can be said).
