PHP: Limit foreach() statement? [closed]

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++) {}

php foreach limit

You can either use

break;

foreach() if ($tmp++ < 2) {}

(the second solution is even worse)

php foreach limit

you should use the break statement

usually it's use this way

$i = 0;foreach($data as $key => $row){    if(++$i > 2) break;}

on the same fashion the continue statement exists if you need to skip some items.
