How can the use of if-else statements in PHP be optimized to avoid unnecessary else branches and improve code readability?

To optimize the use of if-else statements in PHP and avoid unnecessary else branches, you can use early returns to exit the function early if the condition is met. This can help improve code readability by reducing nested if-else blocks. 

function checkValue($value) {
    if ($value === 'A') {
        return 'Value is A';
    }

    if ($value === 'B') {
        return 'Value is B';
    }

    return 'Value is not A or B';
}

echo checkValue('A'); // Output: Value is A
