$_POST is used see below for how.
Firstly, in your form add a hidden feild:
<input type="hidden" name="hasposted" value="true" />
Somewhere in your form.
Then above the form add the following:
<?php
if($_POST['hasposted'] '1'){ $mycheckbox = true; } else { $mycheckbox = false; }
echo '$mytext ' . $mytext . '<br />$mycheckbox '. $mycheckbox;
}
?>
<form method="POST" action="#">
<input type="hidden" name="hasposted" value="true" />
<label>Textbox: <input type="text" value="" name="mytext" /></label><br />
<label>Checkbox: <input type="checkbox" value="1" name="mycheckbox" /><br />
<br />
<input type="submit" value="Post" />
</form>
I've posted links to W3Cschools with information on these and all other Form Elements.

In PHP, the input statement typically refers to how data is received from users, often through forms. The most common way to capture input is by using the $_POST or $_GET superglobals, which retrieve data submitted via HTTP POST or GET methods, respectively.

Additionally, functions like fgets() or fscanf() can be used for reading input from the command line or files.
