Why is it important to use parentheses around the entire IF condition in PHP?

Using parentheses around the entire IF condition in PHP is important because it helps improve code readability and ensures that the condition is evaluated correctly. Without parentheses, the condition may not be evaluated in the intended order, leading to unexpected results. By enclosing the entire condition in parentheses, you can avoid any ambiguity and make your code more clear and maintainable.
