How can the user correct the error in the PHP script to make it functional?

The issue in the PHP script is that the variable $num1 is not defined before it is used in the addition operation. To correct this error, we need to define $num1 and $num2 with some integer values before performing the addition operation. 

$num1 = 10;
$num2 = 5;
$sum = $num1 + $num2;
echo "The sum of $num1 and $num2 is: $sum";
