1、PHP入门二维数组与循环

 1 <?php
 2 $two=array(array(2,3),1=>array(1,2,3),2=>array(4,5,6));
 3     echo $two[1][0];//输出1
 4     echo $two[0][0];//输出2
 5     echo "\r\n";
 6     foreach($two as $key11=>$value12)//二维循环输出
 7     {
 8         echo $value12;
 9         echo "\r\n";
10         foreach($value12 as $key22=>$value22)
11         {
12             echo $value22."\r\n";//使用+号报错
13         }
14     }
15 ?>
