示例1：
<?php
$loptop1['lid'] = 1000;
$loptop1['pic'] = 'img/1.png';
$loptop1['title'] = 'L1';
$loptop1['price'] = 5000;
$loptop1['isOnSale'] = 1;
$loptop1['shelfTime'] = 1234556;
$loptop2['lid'] = 1001;
$loptop2['pic'] = 'img/2.png';
$loptop2['title'] = 'L2';
$loptop2['price'] = 5000;
$loptop2['isOnSale'] = 1;
$loptop2['shelfTime'] = 123444456;
$loptop3['lid'] = 1002;
$loptop3['pic'] = 'img/3.png';
$loptop3['title'] = 'L3';
$loptop3['price'] = 5000;
$loptop3['isOnSale'] = 1;
$loptop3['shelfTime'] = 1243454556;
$loptop4['lid'] = 1003;
$loptop4['pic'] = 'img/4.png';
$loptop4['title'] = 'L4';
$loptop4['price'] = 5000;
$loptop4['isOnSale'] = 1;
$loptop4['shelfTime'] = 1234364556;
$loptop[0] = $loptop1;
$loptop[1] = $loptop2;
$loptop[2] = $loptop3;
$loptop[3] = $loptop4;
for($i=0;$i<count($loptop);$i++){
//echo "编号：$loptop[$i][lid]"; //错误
//echo "编号：" . $loptop[$i]['lid']; //正确，但不推荐
$tmp = $loptop[$i];
echo "编号：$tmp[lid]<br/>";
echo "图片：$tmp[pic]<br/>";
echo "标题：$tmp[title]<br/>";
echo "价格：$tmp[price]<br/>";
echo "是否特价：$tmp[isOnSale]<br/>";
echo "上架时间：" . date("Y-m-d H:i:s",$tmp['shelfTime']) . "<br/>";
}
?>
运行结果：
