本文实例讲述了PHP简单实现二维数组赋值与遍历功能。分享给大家供大家参考，具体如下： 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] = $loptop4; fo/【本文中一些PHP版本可能是以前的，如果不是一定要，建议PHP尽量使用7.2以上的版本】/r($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：
编号：1000 图片：img/1.png 标题：L1 价格：5000 是否特价：1 上架时间：1970-01-15 06:55:56 编号：1001 图片：img/2.png 标题：L2 价格：5000 是否特价：1 上架时间：1973-11-29 18:07:36 编号：1002 图片：img/3.png 标题：L3 价格：5000 是否特价：1 上架时间：2009-05-27 20:02:36 编号：1003 图片：img/4.png 标题：L4 价格：5000 是否特价：1 上架时间：2009-02-11 15:02:36
示例2：
