How can you correctly assign the return value of a PHP function to a variable for further use?

To correctly assign the return value of a PHP function to a variable for further use, you need to call the function and store the return value in a variable. This can be done by using the assignment operator "=" to assign the return value of the function to a variable of your choice. Make sure to call the function before trying to use the variable that holds the return value. 

// Define a function that returns a value
function getSum($a, $b) {
    return $a + $b;
}

// Call the function and assign the return value to a variable
$sum = getSum(5, 3);

// Now you can use the variable $sum which holds the return value of the function
echo $sum; // Output: 8
