一.索引数组
<?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>";输出效果
二.关联数组(不能用for循环)
$contact2 = array( "北京联系人"=>array(1,"高某","A公司","北京市","(010)987654321","gm@linux.com"), "上海联系人"=>array(2,"洛某","B公司","上海市","(021)123456789","lm@apache.com"), "天津联系人"=>array(3,"峰某","C公司","天津市","(022)246802468","fm@mysql.com"), "重庆联系人"=>array(4,"书某","D公司","重庆市","(023)135791357","sm@php.com") ); //创建表格将数组循环输入 echo "<table border="1" width="600" align="center">"; echo "<tr bgcolor="#dddddd">"; echo "<th>编号</th><th>姓名</th><th>公司</th><th>地区</th><th>电话</th><th>EMALL</th>"; echo "</tr>"; foreach ($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>";输出效果:
注意:1.关联数组不能直接用for循环
2.创建表格时 表,行,列的代码都是成对存在的,不要漏掉,不要忘记加斜杠 /
3.能用双引号时尽量用双引号,尤其是录入表格内容时,必须用双引号
