织梦DedeCMS的4个常用函数介绍
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>大家都知道，dedecms支持这样的一些用法，即标记内使用function，调用相关的函数对当前标签返回的内容进行再次处理再显示出来。</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
就拿上面这个标记为例子，本来程序显示数据库某个表的字段senddate，但通过查看数据库发现，senddate只是一大串数字，并不是我们想要的时间格式，PHP语言本身对时间处理是有一些自带的函数，strftime就是php本身自带的函数，当然你也可以扩展，自己编写自己的函数，模板上我们不需要显示这些数字，我们需要按照一定格式转换为我们的时间，这时候就可以使用这个函数进行处理了。</p>

下面我们来分析下dedecms自带一些常用函数的使用方法：</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
<strong>GetCurUrl()</strong></p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
这个估计用到的不是太多，这个函数获得当前运行的脚本地址，使用时候可以通过下列方式：<br>
</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>
代码如下:</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";'>
<br>
{dede:CurUrl runphp='yes'}<br>
@me = GetCurUrl();<br>
{/dede:CurUrl}</div>

<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
返回半角数字的，如果你某个字段信息不希望出现全角数字，可以使用这个函数，例如：<br>
返回的是１２２３４，我希望是半角数字12234，可以这样使用函数：<br>
</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>
<br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>同样这里也有个相反的函数，将html转换为Text的，Html2Text()，其用法类似</span>
