PHP implementation of obtaining form data and HTML embedded PHP script

This article mainly introduces the PHP implementation of obtaining form data and HTML embedding PHP scripts. Interested friends can refer to it. I hope it will be helpful to everyone.

When PHP accepts information submitted through an HTML form, it will save the submitted data in a global array. We can call the system-specific automatic global variable array to obtain these values.

Commonly used automatic global variables are as follows:

1. GET method

Function: Get the data submitted by get method

Format: $_GET["formelement"]

2. POST method

Function: Get the data submitted by post method

Format: $_POST["formelement"]

##3. REQUEST method

Function: Get data submitted in any way. The $_REQUEST automatic global variable contains all GET, POST, COOKIE and FILE data, if you don’t care about the data source.

Format: $_REQUEST["formelement"]
