extract first 3 items in an array

Question

$array = array('item1', 'item2', 'item3', 'item4', 'item5');

here i want to extract only the first three items in the array, and then

$implodes = implode(';', $array);

echo $implodes;

which should output

item1;item2;item3


$i=0;
$new = array();
foreach($array as $arr)
{
  $i++;
  if($i <= 3)
  {
    $new[] = $arr;
  }
}

doesn't look pretty tho

Answer 1

use

array_slice


$output = array_slice($input, 0, 3);

Answer 2

You can use array_slice

$array = array('item1', 'item2', 'item3', 'item4', 'item5');
$implodes = implode(';', array_slice($array,0,3));
echo $implodes;

Answer 3

Use array_slice:

$output = implode(';', array_slice($array, 0, 3));

Answer 4

$array = array_slice( $array , 0 , 3 );

Answer 5

$array = array('item1', 'item2', 'item3', 'item4', 'item5');
$array = array_slice($array, 0, 3);
$implodes = implode(';', $array);
echo $implodes;

Answer 6

$array = array('item1', 'item2', 'item3', 'item4', 'item5');
$output = array_slice($array, 0, 3);
$implodes = implode(';', $array);
echo $implodes;

Answer 7

it can be done also without of any syntax sugar knowledge, but with basic programming skills

$num = 3;
$result='';
for ($i=0,$i<$num,$i++) {
  $result = $result.$array[$i];
  if ($i < $num-1) $result = $result.';';
}

Answer 8

Why not just

$string = sprintf('%s;%s;%s', $array[0], $array[1], $array[2]);

Answer 9

And here is one solution using iterators:

echo implode(';', iterator_to_array(
    new LimitIterator(
        new ArrayIterator(
            array('item1', 'item2', 'item3', 'item4', 'item5')), 0, 3)));

It's not in the spirit of keeping it simple, but it's working. I'd still go with my previous answer though.
