PHP Get Form Method Summary

When PHP accepts information submitted through an HTML form, it saves the submitted data in a global array, and we can get the values by calling the system-specific array of automatic global variables. The common automatic global variables are as follows:
$_get
$_post
$_request

The most commonly used automatic global variables in obtaining form data are $_get and $_post, which obtain data submitted by the Get method and the data submitted through the POST method, respectively. For example, a text box form control called "Txtage", if submitted using the Get method, can be used with the
$_get["Txtage"] or $_get[' txtage ']
Gets the value that it commits.

The $_request automatic global variable contains all the data for GET, POST, cookie, and file, and if you don't care about the data source, you can use the

$_request["Txtage"] or $_request[' txtage ' to get the submitted data.

Here is a simple example of getting the submitted data:

 -->");   Echo ("Your name is:". $_post[' yourname ']); Output name Echo ("
");   Echo ("Your password is:". $_post[' passwd ']); Output Password echo ("
");   Echo ("Your query password question is:". $_post[' question ']); Query password question echo ("
");   Echo ("The answer to your query password is:". $_post[' Question2 ']); Query password answer echo ("
"); Echo ("Your date of birth is:". $_post[' Byear '). " Years. " $_post[' Bmonth ']. "Month". $_post[' Bday '].   "Day"); Date of birth echo ("
");   Echo ("Your gender is:". $_post[' gender ']); Gender Echo ("
"); Echo ("Your hobby is:
"   ); Love foreach ($_post[' hobby '] as $hobby) {echo ($hobby. "
");
}
