How can the EVA principle be applied to improve the structure and efficiency of PHP code?

Issue: The EVA principle (Eliminate, Visualize, Automate) can be applied to improve the structure and efficiency of PHP code by first identifying and removing any redundant or unnecessary code, then visualizing the code flow to identify potential optimizations, and finally automating repetitive tasks to streamline the development process. PHP Code Snippet: 

// Eliminate: Remove redundant code
$variable1 = 10;
$variable2 = 20;
$sum = $variable1 + $variable2;

// Visualize: Visualize code flow for optimization
function calculateSum($a, $b) {
    return $a + $b;
}

$result = calculateSum(10, 20);

// Automate: Automate repetitive tasks
$numbers = [1, 2, 3, 4, 5];
foreach ($numbers as $number) {
    echo $number . "<br>";
}
