What role do quotation marks play in correctly accessing form data within a while loop in PHP?

Quotation marks are essential for correctly accessing form data within a while loop in PHP because they are used to denote strings in PHP. When accessing form data within a while loop, the form field names should be enclosed in quotation marks to ensure that PHP interprets them as strings. This is necessary for correctly retrieving and processing the form data within the loop. 

while ($row = mysqli_fetch_assoc($result)) {
    $name = $row['name']; // Enclose form field name in quotation marks
    $email = $row['email']; // Enclose form field name in quotation marks
    // Process the form data within the while loop
}
