1. Index array
<?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 $contact1 = array( //定义外层数组 array(1,'高某','A公司','北京市','(010)987654321','gm@Linux.com'),//子数组1 array(2,'洛某','B公司','上海市','(021)123456789','lm@apache.com'),//子数组2 array(3,'峰某','C公司','天津市','(022)24680246','fm@mysql.com'), //子数组3 array(4,'书某','D公司','重庆市','(023)13579135','sm@php.com') //子数组4 ); //以HTML表格的形式输出二维数组中的每个元素 echo '<table border="1" width="600" align="center">'; echo '<caption><h1>联系人列表</h1></caption>'; echo '<tr bgcolor="#dddddd">'; echo '<th>编号</th><th>姓名</th><th>公司</th><th>地址</th><th>电话</th><th>EMALL</th>'; echo '</tr>'; //使用双层for语句嵌套二维数组$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);$row++) { echo '<tr>'; //使用内层循环遍历数组$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]);$col++) { echo '<td>'.$contact1[$row][$col].'</td>'; } echo '</tr>'; } echo '</table>';
Output effect
2. Associative array (cannot use for loop)
$contact2 = array( "北京联系人"=>array(1,'高某','A公司','北京市','(010)987654321','gm@linux.com'), "上海联系人"=>array(2,'洛某','B公司','上海市','(021)123456789','lm@apache.com'), "天津联系人"=>array(3,'峰某','C公司','天津市','(022)246802468','fm@mysql.com'), "重庆联系人"=>array(4,'书某','D公司','重庆市','(023)135791357','sm@php.com') ); //创建表格将数组循环输入 echo '<table border="1" width="600" align="center">'; echo '<tr bgcolor="#dddddd">'; echo '<th>编号</th><th>姓名</th><th>公司</th><th>地区</th><th>电话</th><th>EMALL</th>'; echo '</tr>'; foreach ($contact2 as $key=>$value) { echo '<tr>'; //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 '</tr>'; } echo '</table>';
Output effect:
Note:1. Associative arrays cannot be used directly with for loop
2. When creating a table, the codes for tables, rows, and columns exist in pairs. Don’t miss them and don’t forget to add slashes /
3. Try to use double quotes when you can, especially when entering table content, you must use double quotes
