文章是一个简单应用实例利用foreach遍历数组，然后给数组增加一些值进去了，方法比较简单，本文章后来介绍了直接使用array\_push 来给数组增加值两者本人更喜欢后者一些。

例1

<table style="background:#FB7;"> 
 <tbody> 
  <tr> 
   <td>&nbsp;代码如下</td> 
   <td align="center">复制代码</td> 
  </tr> 
  <tr> 
   <td colspan="2"><p>foreach($list as &amp;$value){ </p><p>if(isOnline($value['uid'])){ </p><p>$value['sid'] = '1';</p><p>}else{ </p><p>$value['sid'] = '0';</p><p>}</p><p>$value['likes']='1';</p><p>$sql="SELECT uid,likes,flower&nbsp; FROM ".DB::table("dmember_member_count")." WHERE uid='".$value['uid']."'";</p><p>$fff = DB::query($sql);</p><p>$ffff = DB::fetch($fff);</p><p>//print_r($ffff);</p><p>$value['flower']=$ffff['flower'];</p><p>$value['likes']=$ffff['likes'];</p><p>}</p><p>例子 2，array_push() 函数 </p> 
    <table style="background:#FB7;"> 
     <tbody> 
      <tr> 
       <td>&nbsp;代码如下</td> 
       <td align="center">复制代码</td> 
      </tr> 
      <tr> 
       <td colspan="2"><p>$a=array("Dog","Cat");</p><p>array_push($a,"Horse","Bird");</p><p>print_r($a);</p><p>?&gt;</p><p>输出：</p><p>Array ( [0] =&gt; Dog [1] =&gt; Cat [2] =&gt; Horse [3] =&gt; Bird )</p><p>例子 3</p><p>带有字符串键的数组： </p> 
        <table style="background:#FB7;"> 
         <tbody> 
          <tr> 
           <td>&nbsp;代码如下</td> 
           <td align="center">复制代码</td> 
          </tr> 
          <tr> 
           <td colspan="2"><p>$a=array("a"=&gt;"Dog","b"=&gt;"Cat");</p><p>array_push($a,"Horse","Bird");</p><p>print_r($a);</p><p>?&gt;</p><p>输出：</p><p>Array ( [a] =&gt; Dog [b] =&gt; Cat [0] =&gt; Horse [1] =&gt; Bird )</p></td> 
          </tr> 
         </tbody> 
        </table></td> 
      </tr> 
     </tbody> 
    </table></td> 
  </tr> 
 </tbody> 
</table>
