Comment

This PHP function used to get the username value submitted by a user is:

$_POST['username']

This will assume that the username input field was submitted via a form using the method="post" attribute.

To add the submitted values to a query, you can use the mysqli or PDO extension to construct a SQL query. For example, using mysqli:

$username = $_POST['username'];
$query = "SELECT * FROM users WHERE username='$username'";

Or, using PDO:

$username = $_POST['username'];
$stmt = $pdo->prepare("SELECT * FROM users WHERE username=:username");
$stmt->execute(['username' => $username]);

Note: Always use prepared statements to prevent SQL injection attacks.

Additionally, you can use filter_input() function to get the username value, it helps to prevent SQL injection attacks:

$username = filter_input(INPUT_POST, 'username', FILTER_SANITIZE_STRING);

This will clean the input and stop/prevent any malicious code from being injected.
