修个WordPress同步到新浪微博的插件，兼容性问题一直是麻烦

目前wordpress内容可以同步到微博的插件不多了，这个插件作者一两年不更新，导致无论wordpress版本还是php8.x版本，兼容性都很大，只能手动修改，力求解决问题。

<p>这是一次全新的开始。当初（2010-12-27）开发插件时想法还不够成熟，很多用户数据直接保存在默认的数据库表wp_usermeta，一旦用户多了，会导致该数据库表臃肿无比，对开发插件造成阻碍，更别说大数据分析了，纠结了一年多，终于下定决心完善插件，花了一个星期整理，把社交数据全部无缝地转移到新的数据库表 <?php echo $table_name;?>，可能会花您几分钟时间，但是绝对值得这么做！<strong>提醒：所有用户的同步微博帐号必须重新绑定！</strong></p>
<p><input class="button button-primary" type="button" id="exportConnect" value="点击这里将社交数据转移到新表:<?php echo $table_name;?>" /> <span id="exportStatus">(可能需要一些时间，请耐心等待！)</span></p>
