本文实例讲述了PHP实现登陆并抓取微信列表中最新一组微信消息的方法。分享给大家供大家参考，具体如下：

$_G['wx_g'] = array('init' => array(

"wx_content" => array("weixin_user" => "微信号码", "weixin_pass" => "微信密码")

)

);

wx_login();

$messge_list = get_message_list();

$file_id=$messge_list['item'][0]['multi_item'][0]['file_id'];

//print_r($messge_list);exit;

if(!DB::result_first("select count(weiyi_id) from test.yangang_jiaojing where weiyi_id={$file_id} ")){

DB::query("delete from test.yangang_jiaojing");

foreach ($messge_list['item'][0]['multi_item'] as $key => $val){

$val['title']=mb_convert_encoding($val['title'], 'GBK','UTF-8');

$val['weiyi_id']=mb_convert_encoding($val['file_id'], 'GBK','UTF-8');

$val['des']=mb_convert_encoding($val['digest'], 'GBK','UTF-8');

$val['picurl']=$val['cover'];

$val['detail']=$val['content_url'];

$query_cheng = "INSERT INTO test.yangang_jiaojing(weiyi_id,title,pic_url,detail_url,des)VALUES ({$val['weiyi_id']},'{$val['title']}','{$val['picurl']}','{$val['detail']}','{$val['des']}')";

$count1=DB::query($query_cheng);

}

}
