How to echo certain number of elements from PHP Array

Question

Hello,

If I have an array with say 100 elements.. how can I echo/show the top 5 only for example?

Thank you :)

Answer 1

for ($index=0; $index < min(5, array_count($arr)); $index++)
{
    echo $arr[$index];
}

Answer 2

One option is to use array_slice()

To show each element followed by a line break:

echo implode("<br>", array_slice($array, 0, 5));

not suitable for arrays containing huge amounts of data because the slice will be a copy, but elegant for normal everyday use.

For a resource-conscious approach, see @Svisstack's answer (And now @Gordon's).

Answer 3

See LimitIterator and ArrayIterator

$array    = range(1,100);
$iterator = new LimitIterator(new ArrayIterator($array), 0, 5);
foreach($iterator as $key => $val) {
    echo "$key => $val", PHP_EOL;
}

outputs:

0 => 1
1 => 2
2 => 3
3 => 4
4 => 5
