Retrieving Form Data Using the POST Method in PHP

Now let our form be submitted using the POST method:

form.php<form action="/result.php" method="POST">
  <input name="test1">
  <input name="test2">
  <input type="submit">
</form>

In this case, on the result page, the form data will be stored in the variable $_POST:

result.php<?php
  var_dump($_GET);     // empty array
  var_dump($_POST);    // array with keys test1 and test2
  var_dump($_REQUEST); // array with keys test1 and test2
?>

Задание 1

Using a form, ask the user for their name and age. After submitting the form, display this data on the screen.

Задание 2

Let the form ask the user for a password:

form.php<form action="/result.php" method="POST">
  <input type="password" name="pass">
  <input type="submit">
</form>

Let the correct password be stored in a variable on the result page:

result.php<?php
  $pass = '12345';
?>

Make it so that after submitting the form, the password from the variable and the password from the form are compared on the result page. After the comparison, notify the user whether they entered the correct password or not.

Задание 3

Using three inputs, ask the user for their birth year, month, and day. After submitting the form, determine the day of the week on which the user was born.
