How to display array in table form in php

php displays the array in tabular form:

<?php
//使用array()语句结构将联系人列表中所有数据声明为一个二维数组,默认下标是顺序数字索引
    $contact1 = array(                                             //定义外层数组
    array(1,&#39;高某&#39;,&#39;A公司&#39;,&#39;北京市&#39;,&#39;(010)987654321&#39;,&#39;gm@Linux.com&#39;),//子数组1
    array(2,&#39;洛某&#39;,&#39;B公司&#39;,&#39;上海市&#39;,&#39;(021)123456789&#39;,&#39;lm@apache.com&#39;),//子数组2
    array(3,&#39;峰某&#39;,&#39;C公司&#39;,&#39;天津市&#39;,&#39;(022)24680246&#39;,&#39;fm@mysql.com&#39;),  //子数组3
    array(4,&#39;书某&#39;,&#39;D公司&#39;,&#39;重庆市&#39;,&#39;(023)13579135&#39;,&#39;sm@php.com&#39;)     //子数组4
    );
   //以HTML表格的形式输出二维数组中的每个元素
    echo &#39;<table border="1" width="600" align="center">&#39;;
    echo &#39;<caption><h1 id="联系人列表">联系人列表</h1></caption>&#39;;
    echo &#39;<tr bgcolor="#dddddd">&#39;;
    echo &#39;<th>编号</th><th>姓名</th><th>公司</th><th>地址</th><th>电话</th><th>EMALL</th>&#39;;
    echo &#39;</tr>&#39;;
    //使用双层for语句嵌套二维数组$contact1,以HTML表格的形式输出
    //使用外层循环遍历数组$contact1中的行
    for($row=0;$row<count($contact1);$row++)
    {
        echo &#39;<tr>&#39;;
        //使用内层循环遍历数组$contact1 中 子数组的每个元素,使用count()函数控制循环次数
        for($col=0;$col<count($contact1[$row]);$col++)
        {
            echo &#39;<td>&#39;.$contact1[$row][$col].&#39;</td>&#39;;
        }
        echo &#39;</tr>&#39;;
    }
    echo &#39;</table>&#39;;

The results are as follows:

2, Associative array (for loop cannot be used)

$contact2 = array(
    "北京联系人"=>array(1,'高某','A公司','北京市','(010)987654321','gm@linux.com'),
    "上海联系人"=>array(2,'洛某','B公司','上海市','(021)123456789','lm@apache.com'),
    "天津联系人"=>array(3,'峰某','C公司','天津市','(022)246802468','fm@mysql.com'),
    "重庆联系人"=>array(4,'书某','D公司','重庆市','(023)135791357','sm@php.com')
    );
 //创建表格将数组循环输入
    echo &#39;<table border="1" width="600" align="center">&#39;;
    echo &#39;<tr bgcolor="#dddddd">&#39;;
    echo &#39;<th>编号</th><th>姓名</th><th>公司</th><th>地区</th><th>电话</th><th>EMALL</th>&#39;;
    echo &#39;</tr>&#39;;
    foreach ($contact2 as $key=>$value)
    {
        echo &#39;<tr>&#39;;
//foreach里面嵌套一个for循环也是可以的
        /*for($n=0;$n<count($value);$n++)
        {
            echo "<td>$value[$n]</td>";
        }*/
//foreach里面嵌套foreach

        foreach($value as $mn)
        {
            echo "<td>{$mn}</td>";
        }
        echo &#39;</tr>&#39;;
    }
    echo &#39;</table>&#39;;

The effect is as follows:
