我以表格形式显示我的搜索表单的结果。因此，当用户按名称或位置搜索时，它会在单击搜索按钮时显示结果，但现在我的问题是我想将该数据导出到 csv 文件中，我该如何实现呢？
我已经做了类似的事情来实现它，但它现在只显示 csv 文件，并且页面上没有表格形式的数据：
<form class="form-horizontal" action="testclass.php" method="post" name="userform">
<?php if($_GET[id]){?>
<?php }else{?>
<fieldset>
<legend>Search</legend>
<div class="control-group">
<label class="control-label">Search Term</label>
<div class="controls">
<input type="text" class="span3 search-query" name="term" placeholder="search by name and location">
<button type="submit" class="btn" name="search"><a href="testclass.php">Search</a></button>
</div>
</div>
</form>
这是我的 testclass.php 文件中的代码：
