application/x-www-form-urlencoded

application/x-www-form-urlencoded: The form data is encoded as a name/value pair. This is the standard encoding format.
Multipart/form-data: The form data is encoded as a message, and each control on the page corresponds to a part of the message.
text/plain: Form data is encoded in plain text with no control or formatting characters. The Enctype property of a form is encoded in two common ways: application/x-www-form-urlencoded and Multipart/form-data, which are application/by default. X-www-form-urlencoded.

When action is get, the browser uses x-www-form-urlencoded encoding to convert the form data into a string (Name1=value1&name2=value2 ... ), and then append the string to the URL, using the. Split, to load the new URL.

When the action is post, the browser encapsulates the form data into the HTTP body and then sends it to the server.

If you don't have a type=file control, you can use the default application/x-www-form-urlencoded.

If you have type=file, you will need to use Multipart/form-data. The browser splits the entire form into units of controls and adds Content-disposition (form-data or file) to each section, Content-type (default = Text/plain), name (control name), and so on. and add the separator (boundary).

The above describes the application/x-www-form-urlencoded, including aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
