Slice the array.
切片数组。
foreach(array_slice($section['Article'], 0, 3) as $article ):

It'd be easier to use a for() loop to do this, but to answer the question:
使用 for() 循环来做到这一点会更容易，但要回答这个问题：
<?
$i = 0;
foreach ($section['Article'] AS $article):
if ($i == 3) { break; }
?>
...
<?
$i++;
endforeach
?>

This will help if your array is numerically indexed
如果您的数组是数字索引的，这将有所帮助
foreach($section['Article'] as $i => $article ):
if ($i > 3) break;
Otherwise - manually increment the counter:
否则 - 手动增加计数器：
$i = 0;
foreach($section['Article'] as $article ):
if ($i++ > 3) break;

A foreach loop wouldn't be the best if you need to limit it. Try using a for loop.
如果您需要限制它，foreach 循环不是最好的。尝试使用 for 循环。
<?php
for(i=1; i<=3; i++)
{
$article = $section['Article'];
?>
<tr>
<td><?php if($article['status']== 1){echo $article['title'];} ?></td>
<td><?php if($article['status']== 1){echo ' '.$html->link('View', '/articles/view/'.$article['id']);}?></td>
</tr>
<?php } ?>
This code will make the text loop 3 times.
此代码将使文本循环 3 次。

Awesome one must try this one
很棒的人必须尝试这个
<?php $count = 0; $pages = get_pages('child_of=1119&sort_column=post_date&sort_order=desc'); foreach($pages as $page) {
$count++;
if ( $count < 50) { // only process 10 ?>
<div class="main_post_listing"> <a href="<?php echo get_page_link($page->ID) ?>"><?php echo $page->post_title ?></a><br /></div>
<?php
} } ?>
