+HTTP uses multiple different request types for indicating actions that should be performed on the server. The most common ones
+you will use are:
+- GET     ->  Retrieve a resource
+- POST    ->  Create a new resource
+- PUT     ->  Replace an entire resource
+- PATCH   ->  Update attributes of a resource
+- DELETE  ->  Delete a resource
+
+We have already seen a GET request. The next most common request type is POST. A POST request is structured the same as a GET request, however, it will contain data in the request body:
+```http
+POST /login.php HTTP/1.1
+Host: localhost:8080
+User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:65.0) Gecko/20100101 Firefox/65.0
+Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
+Accept-Language: en-US,en;q=0.5
+Accept-Encoding: gzip, deflate
+Referer: http://localhost:8080/login.php
+Content-Type: application/x-www-form-urlencoded
+Content-Length: 30
+Connection: keep-alive
+Upgrade-Insecure-Requests: 1
+Pragma: no-cache
+Cache-Control: no-cache
+
+username=php&password=password
+```
+The above request is an example login request created by Firefox. You can see in the first line that POST is used to declare the request type.
+At the bottom of the request, the contents contain the user's username and password. A server can easily parse the data and do something with it. In this case, it can authenticate the user.
+
+POST requests are used to send data to a server. A server will process the data and perform an action or store the data.
+
+We have been talking a lot about how a server can process requests and send responses. How do programmers develop a server to handle HTTP requests? With PHP!
+
+PHP was built with web server development in mind. Let us write our first PHP server script.
