How can one effectively iterate through arrays using 'foreach' in PHP?

When iterating through arrays using 'foreach' in PHP, it is important to remember that 'foreach' operates on a copy of the array, so modifying the array within the loop will not affect the original array. To effectively iterate through arrays using 'foreach', you can access both the key and value of each element in the array by using the syntax 'foreach($array as $key => $value)'. This allows you to easily manipulate or access specific elements within the array during iteration. 

$array = [1, 2, 3, 4, 5];

foreach ($array as $key => $value) {
    echo "Key: $key, Value: $value\n";
}
