How can PHP developers avoid using deprecated functions like mysql_list_fields for retrieving column names?

PHP developers can avoid using deprecated functions like `mysql_list_fields` by switching to the MySQLi or PDO extensions, which offer more secure and efficient ways to interact with databases. They can use methods like `mysqli_query` or `PDO::query` to execute SQL queries and retrieve column names using functions like `mysqli_fetch_field_direct` or `PDOStatement::getColumnMeta`. By making this switch, developers can future-proof their code and ensure compatibility with newer PHP versions. 

// Using MySQLi extension to retrieve column names
$mysqli = new mysqli("hostname", "username", "password", "database");
$result = $mysqli->query("SELECT * FROM table");
$columns = $result->fetch_fields();

foreach ($columns as $column) {
    echo $column->name . "<br>";
}
