What are the potential pitfalls of using while loops with mysql_fetch_array to populate an array in PHP?

Using while loops with mysql_fetch_array can lead to performance issues and potential memory leaks if not handled properly. It is recommended to use a more efficient method like PDO or mysqli to fetch data from a database. This will not only improve performance but also provide better security against SQL injection attacks. 

// Example of using PDO to fetch data from a database and populate an array
$db = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

$stmt = $db->query('SELECT * FROM my_table');
$result = $stmt->fetchAll(PDO::FETCH_ASSOC);

foreach ($result as $row) {
    $myArray[] = $row;
}
