印刷只使用Foreach循环多维数组 [英] Printing a multi dimensional array using Foreach loop only

问题描述

  $信息=阵列（
    潘渡格尔=＆GT;阵列（拉维，拉梅什，苏尼），
    SHARDA格尔=＆GT;阵列（neeta，meeta，日图）
）;
 

我要打印输出的一样 -

  

区潘渡格尔和人设拉维

  
  

区潘渡格尔和人设拉梅什

  
  

区潘渡格尔和人设苏尼尔

---

  

区SHARDA格尔和人设neeta
  
  

区SHARDA格尔和人设meeta
  
  

区SHARDA格尔和人位于日图

解决方案

这个是什么：

 的foreach（$信息为$名=＆GT; $位置）{
    的foreach（$地点为$位置）{
        回声区域{$ name}的和人设{$位置}＆LT; BR /＆gt;中;
    }
}
 

这意味着：

• 的数组的第一个维度中的一个回路，


• ，然后，一个环为第二维 - 遍历从第一个得到的数据

$info = array(
    "pandu nagar"  => array("ravi","ramesh","sunil"),
    "sharda nagar" => array("neeta","meeta","ritu")
);

I want to print output like-

Area pandu nagar and person located ravi

Area pandu nagar and person located ramesh

Area pandu nagar and person located sunil

---

Area sharda nagar and person located neeta

Area sharda nagar and person located meeta

Area sharda nagar and person located ritu

解决方案

What about this :

foreach ($info as $name => $locations) {
    foreach ($locations as $location) {
        echo "Area {$name} and person located {$location}<br />";
    }
}

Which means :

• One loop for the first dimension of the array,
• and, then, one loop for the second dimension -- iterating over the data gotten from the first one.
