How can the use of logical operators like AND and OR impact the results of a SQL query in PHP?

Using logical operators like AND and OR in a SQL query can significantly impact the results returned. These operators allow you to specify multiple conditions that must be met for a row to be included in the query results. By using AND, you are specifying that all conditions must be true, while using OR allows for any of the conditions to be true for a row to be included.

$query = "SELECT * FROM table_name WHERE condition1 AND condition2";
$result = mysqli_query($connection, $query);
