Are there any potential pitfalls or limitations when using AND vs. , in MySQL query ordering in PHP?

When using AND in MySQL query ordering in PHP, be cautious of the order of conditions as it can affect the results returned. It is important to properly group conditions using parentheses to ensure the desired logic is followed. Failure to do so can lead to unexpected results or errors in the query execution. 

// Incorrect query ordering using AND
$query = "SELECT * FROM table WHERE condition1 AND condition2 OR condition3";

// Correct query ordering using parentheses
$query = "SELECT * FROM table WHERE (condition1 AND condition2) OR condition3";
