PHP简单实现二维数组赋值与遍历功能示例

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] = $loptop4;
  for($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
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：

<?php
  $stu1['sid'] = 1000;
  $stu1['userName'] = "abc1";
  $stu1['passWord'] = "123456";
  $stu1['email'] = "[e-mail]";
  $stu1['tel'] = "15700769164";
  $stu1['headScu'] = "stu1.png";
  $stu1['sex'] = "M";
  $stu1['regTime'] = 1111223435;
  $stu1['isOnline'] = 1;
  $stu2['sid'] = 1001;
  $stu2['userName'] = "abc2";
  $stu2['passWord'] = "123456";
  $stu2['email'] = "[e-mail]";
  $stu2['tel'] = "15700769165";
  $stu2['headScu'] = "stu2.png";
  $stu2['sex'] = "M";
  $stu2['regTime'] = 122435344;
  $stu2['isOnline'] = 1;
  $stu3['sid'] = 1002;
  $stu3['userName'] = "abc3";
  $stu3['passWord'] = "123456";
  $stu3['email'] = "[e-mail]";
  $stu3['tel'] = "15700769166";
  $stu3['headScu'] = "stu3.png";
  $stu3['sex'] = "M";
  $stu3['regTime'] = 3463464567;
  $stu3['isOnline'] = 0;
  $stu4['sid'] = 1003;
  $stu4['userName'] = "abc4";
  $stu4['passWord'] = "123456";
  $stu4['email'] = "[e-mail]";
  $stu4['tel'] = "15700769167";
  $stu4['headScu'] = "stu4.png";
  $stu4['sex'] = "F";
  $stu4['regTime'] = 235234534;
  $stu4['isOnline'] = 1;
  $stu = [$stu1,$stu2,$stu3,$stu4];
  for($i=0;$i<count($stu);$i++){
    $tmp = $stu[$i];
    echo "编号：$tmp[sid]<br/>";
    echo "用户名：$tmp[userName]<br/>";
    echo "密码：$tmp[passWord]<br/>";
    echo "邮箱：$tmp[email]<br/>";
    echo "手机：$tmp[tel]<br/>";
    echo "头像：$tmp[headScu]<br/>";
    if($tmp['sex'] == "M"){
      echo "性别：男<br/>";
    }
    if($tmp['sex'] == "F"){
      echo "性别：女<br/>";
    }
    echo "注册时间：" . date('Y-m-d H:i:s',$tmp['regTime']) . "<br/>";
    if($tmp['isOnline'] == 1){
      echo "状态：在线<br/>";
    }
    if($tmp['isOnline'] == 0){
      echo "状态：不在线<br/>";
    }
  }
?>

运行结果：
