In PHP database operations, how should one handle the use of logical operators such as AND and OR to ensure accurate and efficient data manipulation?

When using logical operators such as AND and OR in PHP database operations, it is important to properly structure your SQL queries to ensure accurate and efficient data manipulation. This can be done by enclosing the conditions involving logical operators within parentheses to control the order of evaluation. By doing so, you can avoid ambiguity and ensure that the query executes as intended. 

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

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