How can nested loops be used in PHP to combine elements from two arrays?

When we want to combine elements from two arrays using nested loops in PHP, we can use a nested foreach loop. This allows us to iterate over each element in one array and combine it with each element in the second array. By nesting the loops, we can create all possible combinations of elements from the two arrays. 

$array1 = [1, 2, 3];
$array2 = ['a', 'b', 'c'];

foreach ($array1 as $element1) {
    foreach ($array2 as $element2) {
        echo $element1 . $element2 . "<br>";
    }
}
