Operating environment of this tutorial: windows7 system, PHP7.1 version, DELL G3 computer

There are two ways for php to submit data: get and post.

1. Submit data through get

For example: https://www.yisu.com? Parameter name = parameter value & parameter name = parameter value

On the server side (on the side of the requested php file), you can get it through $_ GET. The index value of $_ GET is the parameter name, and the data corresponding to the index is the parameter value. The data submitted through get can be seen in the search bar of the site, and you can also fill in the data in the search bar of the site.

2. Submit data through post

For example, the form is sent through post and can be obtained through $_ POST.

Name: gender:

Data submitted through post is not visible

The difference between post and get

In terms of security, the data submitted by get is visible in the url column, while the data submitted by post is not visible, so post is more secure.

In principle, get submission is a submission of parameters, and post submission is a submission of all parameters as a whole.

In terms of the size of the committed data, the get commit is generally no more than 255bytes, and the size of the post commit depends on the server.

In terms of flexibility, get is very flexible, as long as there is a page jump can pass parameters, post is not flexible, post submission requires the participation of the form.
