How can the use of parentheses affect the evaluation of multiple conditions in PHP if statements?

Using parentheses in PHP if statements can help clarify the order of operations when evaluating multiple conditions. Without parentheses, PHP will evaluate conditions based on operator precedence, which may not always be what you intend. By using parentheses, you can explicitly define the order in which conditions should be evaluated, ensuring the correct logic is applied. 

// Example of using parentheses to clarify the order of operations in an if statement
$condition1 = true;
$condition2 = false;

// Without parentheses
if ($condition1 && $condition2 || $condition1) {
    echo "Condition is true";
}

// With parentheses
if (($condition1 && $condition2) || $condition1) {
    echo "Condition is true";
}
