我在php中创建了一个页面，在不同的列中显示了一些用户数据，如姓名，电子邮件，地址等。数据来自数据库。现在我想导出.csv文件中的所有信息在php中是否有任何解决方案。
下面是在页面上显示数据的代码。
<table width='98%' align="center" id='Categories_Main' cellspacing='0' cellpadding='0' class="table table-striped">
<tr height="25">
<th class="cat_list" colspan="4"><br /><?php echo $this->db->get_modules($cid);?><br /><br /></th>
<th></th>
</tr>
<tr>
<th width="150" style="min-width:55px" class="nowrap center"><a class="hasTip">Gender </a></th>
<th width="150" style="min-width:55px" class="nowrap center"><a class="hasTip">Name</a></th>

如果您想要快速解决方案，请为要导出的数据行使用临时变量 例如，在你的周期之前：
[...]
$this->db->query($sql);
$separator=";"; // Separator to be used in your file
$crlf="\r\n"; // End of line
// Array with the fields to be exported, indexeded on your db fields:
$a_exp=array("gender"="Gender"
,"name"=>"Name"
,"address"=>"Address"
,"email"=>"Email"
,"number"=>"Number"
,"course"=>"Course"
,"price"=>"Price"
,"action"=>"Action");
$csv=""; // Add additional headers here
//Header
while(list($field,$descr)=each($a_exp)) {
$csv.=$descr.$separator;
}
$csv.=$crlf;
while($this->db->fetch_array()) {
// And here you can add the rows
reset($a_exp);
while(list($field,$descr)=each($a_exp)) {
$csv.=$this->db->record[$field].$separator;
}
$csv.=$crlf;
[...]
}
// At the end of the while cycle you can save the file
$f=fopen("/path/to/your/file.csv","a");
fwrite($f,$csv);
fclose($csv);
或者，您可以使用内置的fputcsv函数（http://www.php.net/manual/en/function.fputcsv.php）或现有的CSV导出库。

以与表
中显示的方式相同的方式将数据存储在变量中 $content="col1,col2,col3\n\r";
$content.="data1,data2,data3\n\r";
$content.="data4,data5,data6\n\r";
上面代码的第一行是excel中列的标题
csv中的行\n\r与html表中的</tr><tr>（新行）相同
运行此代码以生成csv文件
$filename = "yourfile.csv";
$f = fopen($filename, 'w');
fwrite($f, $content);
fclose($f);
然后运行以下代码以进行文件下载
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Length: ". filesize("$filename").";");
header("Content-Disposition: attachment; filename=$filename");
header("Content-Type: application/octet-stream; ");
header("Content-Transfer-Encoding: binary");
readfile($filename);
