<?php $ary=array("name","egineer","sonny","tonny","pingk","apple","phone","clone","pink","colle"); foreach($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>';} }; ?>
大家可以运行以后查看结果并分析其巧妙之处~
