从Codeigniter中的mysql导出excel中的数据

Question

我正在将数据从mysql导出到codeigniter中的excel，它在localhost上运行良好，但在服务器上不起作用。在服务器上它仅打印这样的数组。

Array

Answer 1

<?php


// output headers so that the file is downloaded rather than displayed
header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=filename.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', 'user', 'pass');
mysql_select_db("database");
$rows = mysql_query('SELECT something, something, something FROM table');

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

?>

Answer 2

好的，在CI中很简单只需下载csv库，然后

 $this->db->select('*')->from('yourtabl')->where(array('your_conditions')); 
 $query = $this->db->get();
$this->load->helper('csv');
   query_to_csv($query, TRUE, 'yourfilename.csv');
