The efficiency and readability of the PHP script can be improved by utilizing proper indentation, comments, and meaningful variable names. Additionally, breaking down complex tasks into smaller functions can make the code more modular and easier to understand. 

<?php

// Define a function to calculate the sum of two numbers
function calculateSum($num1, $num2) {
    return $num1 + $num2;
}

// Get user input for two numbers
$number1 = $_POST['number1'];
$number2 = $_POST['number2'];

// Calculate the sum of the two numbers
$sum = calculateSum($number1, $number2);

// Display the result
echo "The sum of $number1 and $number2 is: $sum";

?>
