How can you avoid errors when using logical operators in PHP?

When using logical operators in PHP, it's important to ensure that you are using the correct operators and that you are applying them in the right context. To avoid errors, make sure you understand the behavior of operators like && (AND), || (OR), and ! (NOT). Additionally, use parentheses to group expressions when needed to clarify the order of operations.

// Example of using logical operators with correct grouping
$age = 25;
$is_student = true;
$is_senior = false;

if (($age >= 18 && $is_student) || $is_senior) {
    echo "You qualify for a discount.";
} else {
    echo "You do not qualify for a discount.";
}
