How can the output of a PHP while loop be concatenated and stored as a single text field in a database?

To concatenate the output of a PHP while loop and store it as a single text field in a database, you can create a variable to hold the concatenated output within the loop and then insert this variable into the database after the loop has finished executing. 

// Initialize an empty variable to hold the concatenated output
$output = '';

// Start the while loop
while ($row = $result->fetch_assoc()) {
    // Concatenate the desired field from each row
    $output .= $row['field_name'];
}

// Insert the concatenated output into the database
$query = "INSERT INTO table_name (text_field) VALUES ('$output')";
mysqli_query($connection, $query);
