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:

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

价格:5000
是否特价:1
上架时间:1973-11-29 18:07:36

标题:l4
价格:5000
是否特价:1

    }
    if($tmp['isonline'] == 0){
      echo "状态:不在线<br/>";
    }
