在php中将数据导出到csv文件中

我用php制作了一个页面，在不同的列中显示一些用户的数据，如姓名、电子邮件、地址等。这些数据来自数据库。现在我想导出.csv文件中的所有信息。是否有任何php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>

如果需要快速解决方案，请为要导出的数据行使用临时变量。

例如，在您的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（）或现有的CSV导出库。
以与在表中显示相同的方式在变量中存储数据

$content=“col1、col2、col3\n\r”
$content.=“数据1、数据2、数据3\n\r”
$content.=“数据4、数据5、数据6\n\r”

上述代码的第一行是excel中各列的标题
csv中的
\n\r
行与html表中的
（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）

然后运行下面的代码下载文件

头文件（“缓存控制：公共”）
标题（“内容描述：文件传输”）
标题（“内容长度：“.filesize（$filename”）。”；”
标题（“内容处置：附件；文件名=$filename”）
标题（“内容类型：应用程序/八位字节流；”）
标题（“内容传输编码：二进制”）
readfile（$filename）
我希望这将对您有所帮助。我认为，SO上的登录页应该成为一个搜索框。。。
