php 一维数组的循环遍历实现方法

<?php 
/*

 */ 
  $language = array("French",&#39;German&#39;,&#39;Russian&#39;,&#39;Chinese&#39;,&#39;Hindi&#39;,&#39;Quechu&#39;); 
  foreach ($language as $key => $value) { 
    echo $key.&#39;=&#39;.$value.&#39;<br />&#39;; 
  } 
?>

<?php 
  /* 
   * 关联数组的遍历 
   */ 
   $userList = array(&#39;UserName&#39;=>&#39;Lilia&#39;,&#39;Gender&#39;=>&#39;female&#39;,&#39;Age&#39;=>&#39;23&#39;,&#39;School&#39;=>&#39;Peking University&#39;); 
   foreach ($userList as $key => $value)  
  { 
    echo $key.&#39;=&#39;.$value.&#39;<br />&#39;;
