How can PHP developers improve code readability and maintainability when working with arrays, loops, and conditional statements, as demonstrated in the forum thread example?

Issue: PHP developers can improve code readability and maintainability by using meaningful variable names, proper indentation, and comments to explain the logic behind arrays, loops, and conditional statements. Example code snippet: 

// Original code snippet
$nums = array(1, 2, 3, 4, 5);
$total = 0;
foreach ($nums as $num) {
    if ($num % 2 == 0) {
        $total += $num;
    }
}
echo "Total of even numbers: " . $total;

// Improved code snippet
$numbers = array(1, 2, 3, 4, 5);
$totalEvenNumbers = 0;

foreach ($numbers as $number) {
    if ($number % 2 == 0) {
        $totalEvenNumbers += $number;
    }
}

echo "Total of even numbers: " . $totalEvenNumbers;
