How can the use of logical operators improve the readability and efficiency of PHP conditional statements in functions?

Using logical operators such as "&&" and "||" can improve the readability and efficiency of PHP conditional statements in functions by allowing you to combine multiple conditions into a single statement. This can make the code easier to understand and maintain. Additionally, using logical operators can reduce the number of nested if statements, which can improve the overall performance of the function. 

// Example of using logical operators in a PHP function
function checkNumber($num) {
    if ($num >= 0 && $num <= 100) {
        return "Number is between 0 and 100";
    } else {
        return "Number is not between 0 and 100";
    }
}

// Usage
echo checkNumber(50); // Output: Number is between 0 and 100
