这篇文章主要介绍了PHP中余数、取余的妙用,这个是在WEB开发中一个经常使用的小技巧,不管是在表格、ul、li或者是换行等HTML处理中,需要隔几行换行,隔几行加入ul或li的结束标记等时候,特别的有用,需要的朋友可以参考下
- <?php
- $ary=array("name","egineer","sonny","tonny","pingk","apple","phone","clone","pink","colle");
- foreach($ary as $key=>$value){
- $key=$key+1;
- if($key%2==1){echo '<li>';}
- ?>
- <span><?php echo $key.":". $value;?></span>
- <?php
- if($key%2==0){echo '</li>';}
- };
- ?>
second_one
- <?php
- $ary=array("name","egineer","sonny","tonny","pingk","apple","phone","clone","pink","colle");
- foreach($ary as $key=>$value){
- $key=$key;
- if($key%3==0){echo '<li>';}
- ?>
- <span class="<?php echo($key%3); ?>span"><?php echo $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~
