how to shift multiple element off the beginning of array

I have a array contained 20 keys.

$arr = array(
               "1" = "one",
               "2" = "two",
               .
               .
               .
               "20" = "twenty"
            );

Now I want to ignore ten key first, and I want this output :

print_r($output);

// eleven, twelve, ..., twenty

here is one solution. using array_shift($arr), but this solution is not optimized, because I should use 10 time of that function. something like this:

$arr = array_shift($arr); // ignoring first key
$arr = array_shift($arr); // ignoring second key
.
.
.
$arr = array_shift($arr); // ignoring tenth key

there is any better solution ?

It is little similar to you. However, You can also try. See the following example. It would be more comfortable code:

$students = array("one", "two", "three", "four", "five", "six", "more");
$to_be_shifted = 3;
for ($i = 1; $i <= $to_be_shifted; $i++) {
    array_shift($students);
}
print_r($students);

I think you might be looking for array_splice, which directly modifies the array (same as array_shift), instead of returning a new array.

$n = 2;  // number of elements to shift
array_splice($array, 0, $n);

Try this :

$array = array_slice($array, 10);
