PHP: Any function that return first/last N elements of an array

Question

I want a function that will return last/first N element of an array.

For example:

$data = array( \'0\',\'1\',\'2\',\'3\',\'4\',\'5\'         


        

Answer 1

function getItems($data, $length, $startLocation){
   if($startLocation == 'first'){
      return array_slice($data, 0, $length);
   }else if($startLocation == 'last'){
      $offset = count($data) - $length - 1;
      if($offset < 0) $offset = 0;
      return array_slice($data, $offset, $length);
   }
}

Answer 2

You're looking for array_slice() (man page here).

Example:

$arr = array(1, 2, 3, 4, 5);
$slice1 = array_slice($arr, 2); //take all elements from 3rd on
$slice2 = array_slice($arr, 0, 3); //take first three elements
