What are the potential pitfalls of using while loops in PHP when iterating through arrays, as seen in the provided code snippet?

Using while loops to iterate through arrays in PHP can lead to potential pitfalls such as infinite loops if not handled properly. It is crucial to ensure that the loop termination condition is correctly defined to avoid this issue. One way to solve this problem is by using a for loop instead, which provides a clearer structure for iterating through arrays and reduces the risk of infinite loops. 

// Example of iterating through an array using a for loop instead of a while loop
$array = [1, 2, 3, 4, 5];

for ($i = 0; $i < count($array); $i++) {
    echo $array[$i] . "\n";
}
