Question

I’ve two arrays array1 and array2 and I want to add all elements of array2 to the end of array1. array1 contains many items.

The keys are numeric and I don’t want this syntax:

array1 = array1 + array2

or

array1 = SomeArrayFun(array1,array2)

As it takes away CPU times ( as array is created twice )

What I want is:

array1 . SomeAddFun(array2); // This will not create any new arrays

Is there any way to do it?

Answer 1

If you’d like to append data to an existing array you should se array_splice.

With the proper arguments you’ll be able to insert/append the contents of $array2 into $array1, as in the below example.

$array1 = array (1,2,3);
$array2 = array (4,5,6);

array_splice ($array1, count ($array1), 0, $array2);

print_r ($array1);

output:

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
)
