//如限制5条记录；
//没有数字索引时
$i=1;
foreach($list as $val){
if($i>=5) break;
//do
$i++;
}
//有默认索引时
foreach($list as $key=>$val){
if($key>=5) break;

wordpress 可以用自带的查询功能
$query = new WP_Query($args);
$query->set( 'posts_per_page', '5' );//把这行插里面
if ($query->have_posts()): while ($query->have_posts()) : $query->the_post();
