What potential pitfalls should be considered when using the mysql_insert_id function in PHP?

One potential pitfall when using the `mysql_insert_id` function in PHP is that it returns the ID generated by the last query, which may not necessarily be from the current query if multiple queries are executed simultaneously. To ensure that you get the correct ID from the current query, you should use the `mysqli_insert_id` function instead, which is specific to the MySQLi extension in PHP. 

// Connect to the database using MySQLi
$mysqli = new mysqli("localhost", "username", "password", "database");

// Check for connection errors
if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// Execute your insert query
$query = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')";
$mysqli->query($query);

// Get the ID generated by the last insert query
$insert_id = $mysqli->insert_id;

// Use the $insert_id as needed
echo "The ID of the inserted row is: " . $insert_id;

// Close the database connection
$mysqli->close();
