我在 php 中创建了页面，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 中有什么解决方案吗？
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>

如果您想要一个快速的解决方案，请为要导出的数据行使用临时变量。
例如，在你的 while 循环之前：

[...]
$this->db->query($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 中的行与 html 表中的（新行）\n\r相同</tr><tr>

运行此代码以制作 csv 文件

$filename = "yourfile.csv"; $f = fopen($filename, 'w'); fwrite($f, $content); fclose($f);

然后运行以下代码以使文件下载

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);
