组合两个 foreach 循环

我有两个 foreach 循环： 第一个：

        foreach ($items as $key => $item) 
        {   
        $keywords = explode(' ', $qsvarus);
        $title[$key] = preg_replace('/\b('.implode('|', $keywords).')\b(?![^<]*[>])/i', '<b>$0</b>', $title[$key]);
        $infoo[$key] = preg_replace('/\b('.implode('|', $keywords).')\b(?![^<]*[>])/i', '<b>$0</b>', $infoo[$key]);
        echo '<tr><td>'.$title[$key].$infoo[$key].$item.'</tr></td>';
}

2nd one:

foreach ($linkai as $key => $linkas) {
    $i++;
    $a1 = $linkas[1];
$a2 = str_replace("download/", "files/", $a1);
$a3 = str_replace("&","&", $a2);
$a4 = str_replace("amp;nbsp;","nbsp;", $a3);
echo "<div class=\"bgframe".str_replace("/i/", "/IMG/", $a4)."</div></div>";
}

问题是如何使这两个循环显示如下结果：

Result1 from Loop1
Result1 from Loop2
Result2 from Loop1
Result2 from Loop2
Result3 from Loop1
Result3 from Loop2
And so on...

代替：

Result1 from Loop1
Result2 from Loop1
Result3 from Loop1
...
Result1 from Loop2
Result2 from Loop2
Result3 from Loop2

Thanks

您可以使用MultipleIterator http://www.php.net/multipleiterator为了这：

$m = new MultipleIterator();
$m->attachIterator(new ArrayIterator($items), 'item');
$m->attachIterator(new ArrayIterator($linkai), 'linkas');

foreach ($m as $unit) {
    // $unit['item'] contains an entry from $items
    // $unit['linkas'] contains an entry from $linkai

    // your logic here
}
