In the provided PHP code, what are some best practices that could have been implemented to avoid the issue of not displaying values from the $anzahlgesamt array?

The issue in the provided PHP code is that the $anzahlgesamt array is being overwritten within the foreach loop, causing the values to not be displayed correctly. To solve this issue, we can create a new variable to store the sum of values from the $anzahlgesamt array and then use that variable to display the total sum.

// Initialize a new variable to store the sum of values from $anzahlgesamt array
$totalSum = 0;

// Loop through $anzahlgesamt array to calculate the total sum
foreach ($anzahlgesamt as $value) {
    $totalSum += $value;
}

// Display the total sum
echo "Total sum: " . $totalSum;
