What is the significance of using array_combine to merge two arrays in PHP?

When merging two arrays in PHP, the array_combine function is significant because it allows you to merge two arrays into a single array where one array becomes the keys and the other array becomes the values. This function is useful when you have two arrays that you want to combine in a way that preserves the relationship between the elements of the two arrays. 

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

$combinedArray = array_combine($array1, $array2);

print_r($combinedArray);
