Comparison of how get and post are submitted in PHP

In the PHP interview, a high-frequency question is asked how to get and post the way the difference between the submission, so I would like to make a simple comparison from five aspects.

different aspects	POST	GET
Data location	The body of the HTTP	Header
Vmcontext	Ciphertext	Plaintext
Data security	Relatively safe	URL is not secure enough to pass the parameter
Length limit	1024 characters	2 m, adjustable as needed
Application Scenarios	Querying data to the server	Update data

Last Note:

HTTP defines different ways to interact with the server, with 4 basic methods, namely get,post,put,delete.

url full name is a resource descriptor, we can think of: a URL address, which is used to describe a network of resources, and HTTP get,post,put,delete corresponds to the   of this resource; Check  ,  change  ,  add  , delete  4 an operation.

get is typically used to Get/Query resource information, and post is typically used to Update resource information.
