How can different logical operators like AND and OR affect the results of a MySQL database query in PHP?

Using different logical operators like AND and OR in a MySQL database query in PHP can greatly affect the results returned. The AND operator requires both conditions to be true for a row to be included in the result set, while the OR operator only requires one condition to be true. By carefully choosing the logical operators in your query, you can accurately retrieve the desired data from the database. 

// Example query using AND operator
$query = "SELECT * FROM table_name WHERE condition1 AND condition2";

// Example query using OR operator
$query = "SELECT * FROM table_name WHERE condition1 OR condition2";
