foreach($aryas$key=>$value){
$key=$key+1;
if($key%2==1){echo'<li>';}
?>
<span><?phpecho$key.":".$value;?></span>
<?php
if($key%2==0){echo'</li>';}
};
?>
second_one
<?php
$ary=array("name","egineer","sonny","tonny","pingk","apple","phone","clone","pink","colle");
foreach($aryas$key=>$value){
$key=$key;
if($key%3==0){echo'<li>';}
?>
<spanclass="<?phpecho($key%3);?>span"><?phpecho$key.":".$value;?></span>
<?php
if($key%3==2){echo'</li>';}
