Breaking the nested loop [duplicate]
Unlike other languages such as C/C++, in PHP you can use the optional param of break like this:
break 2;In this case if you have two loops such that:
while(...) { while(...) { // do // something break 2; // skip both }}break 2 will skip both while loops.
Doc: http://php.net/manual/en/control-structures.break.php
This makes jumping over nested loops more readable than for example using goto of other languages
Use a while loop
<?php $count = $i = 0;while ($count<5 && $query->posts[$i]) { $j = 0; $post = $query->posts[$i++]; if ($images = get_children(array( 'post_parent' => $post->ID, 'post_type' => 'attachment', 'post_mime_type' => 'image')) ){ while ($count < 5 && $images[$j]) { $count++; $image = $images[$j++]; .. } }}?>
