PHP - get array records by index range

Question

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?

Answer 1

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); 

Answer 2

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));
