这篇文章主要介绍了PHP简单实现二维数组赋值与遍历功能,涉及php数组的简单赋值、遍历、运算、读取等操作使用技巧,需要的朋友可以参考下，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] ";

 echo "图片：$tmp[pic] ";

 echo "标题：$tmp[title] ";

 echo "价格：$tmp[price] ";

 echo "是否特价：$tmp[isOnSale] ";

 echo "上架时间：" . date("Y-m-d H:i:s",$tmp['shelfTime']) . " ";

 }

?>

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

标题：L4

价格：5000

是否特价：1

示例2：

<?php

 $stu1['sid'] = 1000;

 $stu1['userName'] = "abc1";

 $stu1['passWord'] = "123456";

 $stu1['email'] = "2109882885@qq.com";

 $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'] = "2109882886@qq.com";

 $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'] = "2109882887@qq.com";

 $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'] = "2109882888@qq.com";

 $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] ";

 echo "用户名：$tmp[userName] ";

 echo "密码：$tmp[passWord] ";

 echo "邮箱：$tmp[email] ";

 echo "手机：$tmp[tel] ";

 echo "头像：$tmp[headScu] ";

 if($tmp['sex'] == "M"){

 echo "性别：男 ";

 }

 if($tmp['sex'] == "F"){

 echo "性别：女 ";

 }

 echo "注册时间：" . date('Y-m-d H:i:s',$tmp['regTime']) . " ";

 if($tmp['isOnline'] == 1){

 echo "状态：在线 ";

 }

 if($tmp['isOnline'] == 0){

 echo "状态：不在线 ";

 }

 }

?>
