PHP knowledge point 3-HTTP header-The difference between Accept and Content-Type

1.Accept belongs to the request header, and Content-Type belongs to the entity header.
Http headers are divided into general headers, request headers, response headers and entity headers.
The http header structure of the requester: Universal header|Request header|Entity header
The HTTP header structure of the responder: Universal header|Response header|Entity header
2.Accept represents the data type that the sender (client) wants to accept.
For example: Accept: text/xml;
Represents that the data type that the client wants to accept is xml type
Content-Type represents the data type of entity data sent by the sender (client|server).
For example: Content-Type: text/html;
It means the data format sent by the sender is html.
The combination of the two,
Accept:text/xml;
Content-Type:text/html
means that the data type you want to accept is xml format, and the data format of the data sent in this request is html.
