What are the best practices for iterating over arrays in PHP to avoid index access issues?

When iterating over arrays in PHP, it is important to use foreach loops instead of traditional for loops to avoid index access issues. This is because foreach loops automatically handle the iteration process and prevent out-of-bounds errors. By using foreach loops, you can safely access each element in the array without worrying about index boundaries. 

// Example of iterating over an array using foreach loop
$array = [1, 2, 3, 4, 5];

foreach ($array as $value) {
    echo $value . "\n";
}
