如何限制php dom解析结果

我放弃了一些结果，当我放弃时，我得到了50个结果。我想要 要只显示前20个结果，下面是代码，如何限制结果

使用变量继续计算结果，并在计数为

20

时立即从for循环中断

<?php
require 'simple_html_dom.php';

    $url = "http://espncricinfo.com/scores/match-100007";
    $html = file_get_html( $url );

    $posts = $html->find('div[type=tuple]');
$count = 0;
foreach ( $posts as $post ) {
$count++
$matchtitle = $post->find('span[class=desigd]',0);

$matchdate = $post->find('span[class=date]',0);

echo $matchtitle;
echo $matchdate;
if($count == 20)
{
    exit();
}
}
?>

谢谢，先生，它正在工作。小修正$count++应为$count++；

<?php
require 'simple_html_dom.php';

    $url = "http://espncricinfo.com/scores/match-100007";
    $html = file_get_html( $url );

    $posts = $html->find('div[type=tuple]');
$count = 0;
foreach ( $posts as $post ) {
$count++
$matchtitle = $post->find('span[class=desigd]',0);

$matchdate = $post->find('span[class=date]',0);

echo $matchtitle;
echo $matchdate;
if($count == 20)
{
    exit();
}
}
?>
