如何在foeeach遍历二维数组并用.=将值加到一个变量里面

<br />foreach ($posts as $k=>$p){<br />$items.=$p['pro_name'], $p['Discription'], $p['PicUrl'], $p['Url'];<br />}<br />


这是用foreach遍历一个二维数组,我想将所有遍历出来的值都加到 $items上面,然后再foreach外进行打印。

但是这样打印,浏览器什么都不显示。

但是直接在循环里面进行输出,可以正常显示。

<br />foreach ($posts as $k=>$p){<br />echo $items=$p['pro_name'], $p['Discription'], $p['PicUrl'], $p['Url'];<br />}<br />


这样可以正常显示,这样我该怎么实现将所有遍历出来的值都加到 $items上面,然后再foreach外进行打印?
