PHP: Limit foreach() statement? [closed]

by

There are many ways, one is to use a counter:

$i = 0;
foreach ($arr as $k => $v) {
    /* Do stuff */
    if (++$i == 2) break;
}

Other way would be to slice the first 2 elements, this isn’t as efficient though:

foreach (array_slice($arr, 0, 2) as $k => $v) {
    /* Do stuff */
}

You could also do something like this (basically the same as the first foreach, but with for):

for ($i = 0, reset($arr); list($k,$v) = each($arr) && $i < 2; $i++) {
}
