PHP中余数、取余的妙用

<"name","egineer","sonny","tonny","pingk","apple","phone","clone","pink","colle");
foreach($ary as $key=>$value){
$key=$key+1;
if($key%2==1){echo '<li>';}
  ":". $value;"htmlcode">

 <"name","egineer","sonny","tonny","pingk","apple","phone","clone","pink","colle");
foreach($ary as $key=>$value){
$key=$key;
if($key%3==0){echo '<li>';}
  "<"><":". $value;?></span>
 
<?php
 if($key%3==2){echo '</li>';}
};
 ?>
