微信微信到以前几个文件

data\tpl\web\default\system\common.tpl.php 
framework\function\sms.func.php
web/source/system/common.ctrl.php
web/source/utility/verifycode.ctrl.php
web/source/user/register.ctrl.php

其实发送短信的文件：sms.func.php 核心代码如下：

function sms_send(mobile = '',content = '',signature = '',check = true) {

        global_W;
     
       setting = setting_load('sms');
        
        if(empty(setting['sms'])){
               return error(1, "未设置短信接口，无法发送短信!");
        }

       config =setting['sms'];
        
       row = pdo_fetch("SELECT `notify` FROM " . tablename('uni_settings') . " WHERE uniacid = :uniacid", array(':uniacid' =>_W['uniacid']));
       row['notify'] = @iunserializer(row['notify']);
        smsconfig=array("balance"=>999,"signature"=>_W['setting']['sitename']);
        if (!empty(row['notify']) && !empty(row['notify']['sms'])) {
             smsconfig =row['notify']['sms'];
        }
       //if(check){
       //    if (intval(smsconfig['balance'])<=0){
       //        return error(1, "短信条数不足，请联系客服人员".row['notify']['sms']['balance']);
       //    }
       //}
        if(empty(signature)){
           signature = "";
        }
   
       
        username =config['ihuyi_username'];
        pwd =config['ihuyi_pwd'];
        target = "http://jiekou.56dxw.com/sms/webinterface.aspx";
        post_data = "username=" .username . "&userpwd=" .pwd . "&handtel=" .mobile . "&sendcontent=" . rawurlencode(content);
        result = file_get_contents(target.post_data);
        xml = simplexml_load_string(result['code'], 'SimpleXMLElement', LIBXML_NOCDATA);
        msg = (string)xml->msg;
         
         if(result=='0'){
             row['notify']['sms']['balance'] = intval(row['notify']['sms']['balance']) -1;
              pdo_update('uni_settings',array('notify'=>  iserializer(row['notify'])), array('uniacid' =>_W['uniacid']));
              return true;
         }
         return error(1,message);
