How can you ensure the syntax and functionality of an UPDATE query in PHP when dealing with multiple database connections?

When dealing with multiple database connections in PHP, it is important to specify the connection to be used for the UPDATE query to ensure the syntax and functionality. This can be done by passing the connection object as a parameter to the query execution function. By explicitly specifying the connection, you can avoid any potential conflicts or errors that may arise from using the wrong connection. 

// Assuming $conn1 and $conn2 are the database connection objects

// Update query using $conn1 connection
$updateQuery = "UPDATE table_name SET column_name = 'new_value' WHERE condition";
$conn1->query($updateQuery);

// Update query using $conn2 connection
$updateQuery2 = "UPDATE table_name SET column_name = 'new_value' WHERE condition";
$conn2->query($updateQuery2);
