How can PHP developers ensure that all values from a database query are properly retrieved and stored in an array?

PHP developers can ensure that all values from a database query are properly retrieved and stored in an array by iterating through the result set and fetching each row as an associative array. This allows developers to access each column value by its corresponding key, ensuring that no data is missed or incorrectly stored. 

// Assume $conn is a valid database connection

$query = "SELECT * FROM table_name";
$result = mysqli_query($conn, $query);

$data = array();

if(mysqli_num_rows($result) > 0) {
    while($row = mysqli_fetch_assoc($result)) {
        $data[] = $row;
    }
}

// $data now contains all rows from the query result stored as associative arrays
