What are the benefits of using logical operators like OR and AND in SQL queries for PHP applications?

Using logical operators like OR and AND in SQL queries for PHP applications allows for more complex and precise data retrieval. By combining conditions using these operators, you can filter data based on multiple criteria, making your queries more efficient and targeted. This can help improve the performance of your application and ensure that you are retrieving only the data that meets specific requirements. 

// Example SQL query using logical operators AND and OR
$query = "SELECT * FROM users WHERE (age > 18 AND gender = 'female') OR (city = 'New York')";
$result = mysqli_query($connection, $query);

// Process the query result
if(mysqli_num_rows($result) > 0) {
    while($row = mysqli_fetch_assoc($result)) {
        // Process each row of data
    }
} else {
    echo "No results found.";
}
