這篇文章主要介紹了PHP簡單實現二維數組賦值與遍歷功能,涉及php數組的簡單賦值、遍歷、運算、讀取等操作使用技巧,需要的朋友可以參考下

#本文實例講述了PHP簡單實作二維數組賦值與遍歷功能。分享給大家供大家參考,具體如下:

範例1:

<?php
  $loptop1[&#39;lid&#39;] = 1000;
  $loptop1[&#39;pic&#39;] = &#39;img/1.png&#39;;
  $loptop1[&#39;title&#39;] = &#39;L1&#39;;
  $loptop1[&#39;price&#39;] = 5000;
  $loptop1[&#39;isOnSale&#39;] = 1;
  $loptop1[&#39;shelfTime&#39;] = 1234556;
  $loptop2[&#39;lid&#39;] = 1001;
  $loptop2[&#39;pic&#39;] = &#39;img/2.png&#39;;
  $loptop2[&#39;title&#39;] = &#39;L2&#39;;
  $loptop2[&#39;price&#39;] = 5000;
  $loptop2[&#39;isOnSale&#39;] = 1;
  $loptop2[&#39;shelfTime&#39;] = 123444456;
  $loptop3[&#39;lid&#39;] = 1002;
  $loptop3[&#39;pic&#39;] = &#39;img/3.png&#39;;
  $loptop3[&#39;title&#39;] = &#39;L3&#39;;
  $loptop3[&#39;price&#39;] = 5000;
  $loptop3[&#39;isOnSale&#39;] = 1;
  $loptop3[&#39;shelfTime&#39;] = 1243454556;
  $loptop4[&#39;lid&#39;] = 1003;
  $loptop4[&#39;pic&#39;] = &#39;img/4.png&#39;;
  $loptop4[&#39;title&#39;] = &#39;L4&#39;;
  $loptop4[&#39;price&#39;] = 5000;
  $loptop4[&#39;isOnSale&#39;] = 1;
  $loptop4[&#39;shelfTime&#39;] = 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][&#39;lid&#39;]; //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[&#39;shelfTime&#39;]) . "<br/>";
  }
?>

運行結果:

编号:1000

标题:L1
价格:5000
是否特价:1
上架时间:1970-01-15 06:55:56
