PHP: Select part of array

Question

I have an array:

$array = [1,2,3,4,5,6,7,8];

How do I select a subset of the array, to return just [2,3,4,5,6]?

I think it should be something along the lines of:

$array[2-6]

but that's not working

Googling php array subset -- first result = 'array_slice — Extract a slice of the array'. It makes me wonder why asking on SO is preferred to Googling :( — Prasanth

Sorry if you through this was a silly question. I am just learning PHP and didn't think of the word "subset" until I was writing this post. I did look for an answer online before posting. — AllieCat

You want to use array_slice($array, 1, 5)

To get the value without modifications in $array, you must use: array_slice($array, 1, 5, true) (cf. last parameter preserve_keys).

Use array_slice():

$array = [1,2,3,4,5,6,7,8];    
$output = array_slice($array, 1, 5);

print_r($output);

Output:

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

Use array_filter

function filter_arr($value) {
    return 1 < $value && $value < 7;
}
array_filter($array, "filter_arr");

His attempted solution suggests that he's subsetting by index, not values.
