UCHOME现在很多论坛都是在使用该开源程序，其中上传头像模块很是好使，下面作者就使用网上有的分离出来UCHOME的AVATAR上传插件进行方法整合。

首先是将下载的插件包放到项目中：(这边先废话下，采用的是YII框架进行整合的，本来想放进YII的扩展包里面的，但是测试后发现不得行，就放到项目中进行整合了。)

1、将下载下来的插件包放入如下位置：

2、定义配置下载包中的配置文件，配置信息要按照个人的去进行配置了，作者的配置信息如下：configs.global.php

<span>php
    </span><span>error_reporting</span>(7<span>);
    @</span><span>header</span>("Content-type: text/html; charset=utf-8"<span>);
    </span><span>session_cache_limiter</span>('public, must-revalidate'<span>);
    date_default_timezone_set(</span>'PRC'<span>);
    
    </span><span>/*</span><span>
    |---------------------------------------------------------------
    | PHP ERROR REPORTING LEVEL
    |---------------------------------------------------------------
    </span><span>*/</span>
    <span>//</span><span>    error_reporting(E_ALL);</span>
    
    <span>define</span>('UC_API', 'http://'.<span>$_SERVER</span>['HTTP_HOST'].'/avatar'<span>);
    </span><span>define</span>('UC_API_EXEC','http://'.<span>$_SERVER</span>['HTTP_HOST'].'/avatar/index.php');<span>//</span><span>执行存储操作的文件</span>
    <span>define</span>('UC_DATAURL', UC_API.'/data'<span>);
    </span><span>define</span>('UC_DATADIR', 'data/');<span>//</span><span>图片存放相对地址</span>
?>

重要的是下面4个define里面的配置信息。

3、在YII的Controller.php基类中增加2个方法：

　　1.第一个方法是用来初始化页面头像和FLASH上传插件的：

<span>/*</span><span>*
 * 整合UCHOME分离出来的头像上传插件
 * @param $uid 程序中用户的ID int类型
 * @return Array('avatarUrl','flashUrl');
 </span><span>*/</span>
<span>public</span> <span>function</span> avatar(<span>$uid</span><span>){
    </span><span>$avatarPath</span> = Yii::app() -> request ->baseUrl.'/avatar/';<span>//</span><span>获取UCAVATAR插件引入包路径</span>
    <span>require_once</span>(<span>$avatarPath</span>.'/configs.global.php');<span>//</span><span>引入UCAVATAR配置文件</span>
    <span>require_once</span>(<span>$avatarPath</span>.'/avatar.php');<span>//</span><span>引入UCAVATAR核心类</span>
    <span>$objAvatar</span> = <span>new</span><span> Avatar();
    </span><span>$personAvatarUrl</span>=<span>$this</span>->getAvatar(<span>$uid</span>);<span>//</span><span>获取用户头像</span>
    <span>$uc_avatarflash</span> = <span>$objAvatar</span>->uc_avatar(<span>$uid</span>, (<span>empty</span>(<span>$_SCONFIG</span>['avatarreal'])?'virtual':'real'));<span>//</span><span>获取上传头像FLASH插件地址</span>
    <span>return</span> <span>array</span>('personAvatarUrl'=><span>$personAvatarUrl</span>,'avatarFlashUrl'=><span>$uc_avatarflash</span><span>);
}</span>

　　2.第二个方法是用来获取不同规格的头像路径的：

    <span>/*</span><span>*
     * 获取用户上传的头像
     * @param $uid
     * @param $size 值为：small、middle、big
     * @return String avatar URL
     * @example $size 默认获取big大图
     </span><span>*/</span>
    <span>public</span> <span>function</span> getAvatar(<span>$uid</span>,<span>$size</span>='big'<span>){
        </span><span>$uid</span> = <span>sprintf</span>('%09d', <span>$uid</span><span>);
        </span><span>$dir1</span> = <span>substr</span>(<span>$uid</span>, 0, 3<span>);
        </span><span>$dir2</span> = <span>substr</span>(<span>$uid</span>, 3, 2<span>);
        </span><span>$dir3</span> = <span>substr</span>(<span>$uid</span>, 5, 2<span>);
        </span><span>//</span><span>获取头像文件在系统中的绝对位置</span>
        <span>$avatarUrl</span>=<span>$_SERVER</span>['DOCUMENT_ROOT'].'/avatar/data/avatar/'.<span>$dir1</span>.'/'.<span>$dir2</span>.'/'.<span>$dir3</span>.'/'.<span>substr</span>(<span>$uid</span>, -2).'_avatar_'.<span>$size</span>.'.jpg'<span>;
        </span><span>//</span><span>检测是否存在有上传头像</span>
        <span>if</span> (<span>file_exists</span>(<span>$avatarUrl</span>)){<span>//</span><span>有,输出头像的URL地址</span>
            <span>return</span> 'http://'.<span>$_SERVER</span>['HTTP_HOST'].'/avatar/data/avatar/'.<span>$dir1</span>.'/'.<span>$dir2</span>.'/'.<span>$dir3</span>.'/'.<span>substr</span>(<span>$uid</span>, -2).'_avatar_'.<span>$size</span>.'.jpg'<span>;
        }</span><span>else</span>{<span>//</span><span>无,输出默认头像地址</span>
            <span>return</span> 'http://'.<span>$_SERVER</span>['HTTP_HOST'].'/avatar/images/noavatar_'.<span>$size</span>.'.gif'<span>;
        }
    }</span>

到此整合UCHOME的头像上传插件就基本完成了，下面进行测试，测试代码如下：

<span>$avatar</span>=<span>$this</span>->avatar(1000<span>);
</span><span>$pic</span>=<span>$avatar</span>['personAvatarUrl'<span>];
</span><span>$avatarFlash</span> =<span>$avatar</span>['avatarFlashUrl'];

前台页面调用的测试信息如下：
