What are potential pitfalls when incrementing array keys in PHP loops?

When incrementing array keys in PHP loops, a potential pitfall is that the loop may skip over keys if they are not incremented correctly. To avoid this issue, it's important to use the correct method to increment keys in the loop, such as using the `++` operator or the `array_keys()` function to retrieve all keys and then incrementing them. 

$array = ['a', 'b', 'c'];

foreach ($array as $key => $value) {
    // Increment key using the ++ operator
    $newKey = $key + 1;
    echo "Key: $newKey, Value: $value\n";
}
