What best practices should be followed when handling boolean values in conditional statements in PHP?

When handling boolean values in conditional statements in PHP, it is best practice to explicitly check for true or false values rather than relying on truthy or falsy values. This helps to ensure that the code is clear and easy to understand for other developers. Additionally, using strict comparison operators (=== and !==) can prevent unexpected behavior when comparing boolean values.

// Bad practice
if ($boolean) {
    // Do something
}

// Good practice
if ($boolean === true) {
    // Do something
}
