I. Contact and difference between get and post
1. Contact for Get and post
Both GET and POST create arrays (for example, array (key = value, Key2 = value2, Key3 = Value3, ...) ）。 This array contains key/value pairs, where the key is the name of the form control, and the value is the input data from the user.
Get and POST are treated as $_get and $_post. They are hyper global variables , which means that access to them does not need to be scoped-no special code is required, and you can access them from any function, class, or file.
