When php accepts information submitted through an HTML form, it saves the submitted data in a global array. we can call the system-specific automatic global variable array to obtain these values. Common automatic global variables are as follows:
$ _ GET
$ _ POST
$ _ REQUEST

In getting form data, the most common automatic global variables are $ _ GET and $ _ POST, which respectively obtain the data submitted through the GET method and the data submitted through the POST method. For example, if a text box form control named "txtAge" is submitted using the GET method, you can use
$ _ GET ["txtAge"] or $ _ GET ['txtage']
Obtain the submitted value.

$ _ REQUEST the automatic global variable contains all GET, POST, COOKIE, and FILE data. if you do not care about the data source, you can use

$ _ REQUEST ["txtAge"] or $ _ REQUEST ['txtage'] to obtain submitted data.

The following is a simple example of getting submitted data:

 "); Echo (" Your name is: ". $ _ POST ['yourname']); // Output name echo ("
"); Echo (" your password is: ". $ _ POST ['passwd']); // output password echo ("
"); Echo (" Your query password problem is: ". $ _ POST ['question']); // query password problem echo ("
"); Echo (" The answer to your query password is: ". $ _ POST ['question2']); // echo ("
"); Echo (" your date of birth is :". $ _ POST ['byear ']. "Year ". $ _ POST ['bmonth']. "Month ". $ _ POST ['bday']. "Day"); // date of birth echo ("
"); Echo (" your gender is: ". $ _ POST ['gender']); // gender echo ("
