Implementation example of php two-dimensional array assignment and traversal function

This article mainly introduces the simple implementation of two-dimensional array assignment and traversal functions in PHP, involving the simple assignment, traversal, operation, reading and other operation techniques of PHP arrays. Friends who need it can refer to it

The example in this article describes the simple implementation of two-dimensional array assignment and traversal functions in PHP. Share it with everyone for your reference, the details are as follows:

Example 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/>";
  }
?>

Running results:

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
