PHP - get array records by index range

HI there,

Is there any PHP native function which returns the range of records from the array based on the start and end of the index?

i.e.:

array(0 => 'a', 1 => 'b', 2 => 'c', 3 => 'd');

and now I would like to only return records between index 1 and 3 (b, c, d).

Any idea?

By using array_intersect_key

$myArray = array(0 => 'a', 1 => 'b', 2 => 'c', 3 => 'd');
$arrayRange = array('1', '2', '3');

// this can also be used if you have integer only array values
// $arrayRange = range(1,3); 

$newArray = array_intersect_key($myArray, array_flip($arrayRange));

print_r($newArray);  // output: Array ( [1] => b [2] => c [3] => d )

$array1 = array(1,2,3,4,5,6,23,24,26,21,12);

    foreach(range ($array1[0],$array1[5]) as $age){
        echo "Age: {$age}<br />";
    }

you should get the following output:

Age: 1

Age: 2

Age: 3

Age: 4

Age: 5

Age: 6

there is a task for array_slice

array array_slice ( array $array , int $offset [, int $length [, bool $preserve_keys = false ]] )

example:

$input = array("a", "b", "c", "d", "e");

$output = array_slice($input, 2);      // returns "c", "d", and "e"
$output = array_slice($input, -2, 1);  // returns "d"
$output = array_slice($input, 0, 3);   // returns "a", "b", and "c"

// note the differences in the array keys
print_r(array_slice($input, 2, -1));
print_r(array_slice($input, 2, -1, true));

Couldn't you do that with e.g. array_slice?

$a = array(0 => 'a', 1 => 'b', 2 => 'c', 3 => 'd');
array_slice($a, 1, 3);
