我使用下面的代码。但是在tmp中创建的文件没有下载。

 $error = fopen(/tmp/error.csv);
     $write[] = "hello";
     $dest_file_path="/tmp/error.csv";
        $dest_file_name="error.csv";
        if(!empty($write))
        {
            $flag = FALSE;
            fputcsv($error,$write,";");
            fclose($error);
            header("Content-Transfer-Encoding: Binary");
            header("Content-length: ".filesize($dest_file_path));
            header('Content-Type: text/csv');
            header('Content-Disposition: attachment; filename="'.$dest_file_name.'"');
            readfile($dest_file_path);
        }

问题是fopen()需要2个参数。

根据手册:

<?php
$handle = fopen("c:\\folder\\resource.txt", "r");
?>

所以这一行:

$error = fopen(/tmp/error.csv);

应该读作(缺少引号,因为你想写入文件,w

$error = fopen('/tmp/error.csv', 'w');

您可能需要调整路径,以达到以下效果:

$error = fopen('/var/user/you/tmp/error.csv', 'w');

$error = fopen('/var/user/you/public_html/tmp/error.csv', 'w');

如果你有错误报告,它会发出类似的信号:

  

警告:fopen()需要至少2个参数,在第x行的/path/to/file.php中给出1

error reporting添加到文件的顶部,这有助于查找错误。

<?php 
error_reporting(E_ALL);
ini_set('display_errors', 1);

旁注:错误报告应仅在暂存时完成,而不是生产。


手册中的更多示例:

<?php
$handle = fopen("/home/rasmus/file.txt", "r");
$handle = fopen("/home/rasmus/file.gif", "wb");
$handle = fopen("http://www.example.com/", "r");
$handle = fopen("ftp://user:password@example.com/somefile.txt", "w");
?>

试试这段代码

// output headers so that the file is downloaded rather than displayed
header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=data.csv');

// create a file pointer connected to the output stream
$output = fopen('php://output', 'w');

// output the column headings
fputcsv($output, array('Column 1', 'Column 2', 'Column 3'));

// fetch the data
mysql_connect('localhost', 'username', 'password');
mysql_select_db('database');
$rows = mysql_query('SELECT field1,field2,field3 FROM table');

// loop over the rows, outputting them
while ($row = mysql_fetch_assoc($rows)) fputcsv($output, $row);
