Any PHP developer needs to have an
adequate understanding of the HTTP protocol. The differences between GET
and POST are an indispensable part of the HTTP protocol learning. Here
are the major differences between the two requests:
GET allows
displaying the submitted data as part of the URL. This is not the case
when using POST as during this time the data is encoded in the request.
The maximum number of characters handled by GET is limited to 2048. No such restrictions are imposed on POST.
GET provides support for only ASCII data. POST, on the other hand, allows ASCII, binary data, as well as other forms of data.
Typically, GET is used for retrieving data while POST is used for inserting and updating data.
