<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>有时候我们对于一个网站源码里面的文章发布时间日期需要进行修改，但是一个一个的修改是不现实的，那么此时就需要批量修改文章发布时间。<br>
1、首先是<strong>SQL语句</strong>：</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
<span><u>复制代码</u></span>
</div>
<p>
代码如下:</p>
</div>
<div class="msgborder" id="phpcode3" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
update dede_archives set pubdate= 1308240000 where id>=1 and id<=10;<br>
update dede_archives set senddate= 1405382400 where id>=1 and id<=10;</div>
<p>
<br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>解释一下上面两行代码，功能就是把ID号从1到10的文章发布日期由2011年6月17日修改到2014年7月15日。</span><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>其中“pubdate= 1308240000 ”和“senddate= 1405382400” 中的数字为“Unix时间(Unixtimestamp) ” 这个把日期转换成时间戳的地址，可以使用php的</span></p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
<span><u>复制代码</u></span>

代码如下:</p>
</div>
<div class="msgborder" id="phpcode4" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
strtotime("2014-07-15 18:25:20");</div>
<p>
<span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>来实现，这里不要忘了php中需要设置时区</span></p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
