What are the potential pitfalls of using durchnummerierte Variablen in PHP code, and why is it recommended to use arrays instead?

Using durchnummerierte (numbered) variables in PHP code can lead to code that is difficult to maintain and scale. It is recommended to use arrays instead because arrays allow you to store multiple values under a single variable, making your code more organized and easier to manage. Arrays also provide built-in functions for sorting, searching, and manipulating data, which can streamline your code and improve efficiency. 

// Using arrays instead of durchnummerierte variables
$numbers = [1, 2, 3, 4, 5];

// Accessing values in the array
echo $numbers[0]; // Output: 1
echo $numbers[2]; // Output: 3

// Adding a new value to the array
$numbers[] = 6;
echo $numbers[5]; // Output: 6

// Looping through the array
foreach ($numbers as $number) {
    echo $number . " ";
}
// Output: 1 2 3 4 5 6
