Wrapping 3 objects or less inside a while / foreach in PHP
- by DarkGhostHunter
Simple question. I have an array of 21 elements, and show every three of them inside a <div> block. The code is something like this:
<?php
$faces= array(
1 => 'happy',
2 => 'sad',
(sic)
21 => 'angry'
);
$i = 1;
foreach ($faces as $face) {
echo $face;
$i++;
}
?>
The problem lies when this array doesn't have 21 elements, sometimes it gets 24, an other times 17. How I wrap every three of them, and wrap alone the rest? I came up with using switch and case, but that works only when there are 21 elements only. I think I could count them beforehand and put a closing in the last one (even if it is a group of one element).
