谢谢您正在打开csv文件并编写一些内容，然后执行查询。那你怎么才能把这些邮件作为输出呢？。试试这段代码，它会给出你需要的准确结果
<?php
$conn=mysqli_connect("localhost","root","","table_name");// connection to db
if(isset($_POST['export_test'])){
$sql="select email from address";// select query
$res=mysqli_query($conn,$sql);
$line .= "\n"; // new line
$filename='email.csv';// create csv file if dosent exist
$fp = fopen($filename, "w");// open the csv file to write
while($row=mysqli_fetch_array($res)){
$line = "";
$comma = "";
$line .= $comma . '"' . str_replace('"', '""', $row['email']) . '",';
$comma = ",";
$line .= "\n";
fputs($fp, $line); // put the line into csv
}
fclose($fp);
header('Content-Type: text/csv; charset=utf-8');// to download the email.csv
header('Content-Disposition: attachment; filename=email.csv');
}
?>
谢谢大家!
