HTTP Content-type Comparison Table

Content-Type, content type, generally refers to the Content-Type in the web page, which is used to define the type of network file and the web page encoding. It determines how the browser will read this file in what form and encoding, such as when using PHP to output image files, JSON data, XML files, and other non-HTML content, you must use the header function to specify the Content-Type to meet the needs of outputting an image or other specified content types.
