What are the potential pitfalls or drawbacks of using bitwise operators in PHP, especially in terms of readability and maintainability of code?

Using bitwise operators in PHP can make code less readable and harder to maintain, as their functionality might not be immediately obvious to other developers. To improve readability and maintainability, consider using more explicit conditional statements or functions to achieve the same result as bitwise operations. 

// Example of improving readability by using explicit conditional statements
$permissions = 5;

// Using bitwise operators
if ($permissions & 4) {
    echo "User has write access";
}

// Improved readability with explicit conditional statements
if ($permissions === 4 || $permissions === 5) {
    echo "User has write access";
}
