How can developers ensure they are using the correct SQL syntax for creating and querying temporary tables in PHP, particularly when switching between different database systems?

Developers can ensure they are using the correct SQL syntax for creating and querying temporary tables in PHP by utilizing a database abstraction layer or ORM that handles the differences between database systems. This allows developers to write database queries in a uniform way without worrying about the specific syntax differences between systems. 

// Example using PDO and MySQL as the database system
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

// Create a temporary table
$pdo->exec("CREATE TEMPORARY TABLE temp_table (id INT, name VARCHAR(50))");

// Query the temporary table
$stmt = $pdo->query("SELECT * FROM temp_table");
while ($row = $stmt->fetch()) {
    echo $row['id'] . ' - ' . $row['name'] . '<br>';
}
