PHP导出数据到CSV文件

后台往往需要导出各种数据到 Excel文档中。通常我们是导出 .csv文件格式，PHP导出函数参考代码如下：/**
* 导出数据到CSV文件
*
* @param array $data 二维数组（模拟数据表记录）
* @param array $titleList 标题数组列表
* @param string $fileName CSV文件名
*/
function csv_export(&$data, $titleList = array(), $fileName = '')
{
ini_set("max_execution_time", "3600");
$csvData = '';

// 标题
$nums = count($titleList);
for ($i = 0; $i < $nums - 1; $i++)
{
$csvData .= '"' . $titleList[$i] . '",';
}
$csvData .= '"' . $titleList[$nums - 1] . "\"\r\n";

foreach ($data as $key => $row)
{
$i = 0;
foreach ($row as $_key => $_val)
{
$_val = str_replace("\"", "\"\"", $_val);
if ($i < ($nums - 1))
{
$csvData .= '"' . $_val . '",';
}
elseif ($i == ($nums - 1))
{
$csvData .= '"' . $_val . "\"\r\n";
}
$i++;
}
unset($data[$key]);
}

$csvData = mb_convert_encoding($csvData, "cp936", "UTF-8");
$fileName = empty($fileName) ? date('Y-m-d-H-i-s', time()) : $fileName;
$fileName = $fileName . '.csv';
header("Content-type:text/csv;");
header("Content-Disposition:attachment;filename=" . $fileName);
header('Cache-Control:must-revalidate,post-check=0,pre-check=0');
header('Expires:0');
header('Pragma:public');
echo $csvData;
die();
}
使用示例：
$data = array(
array(
'name' => 'jake',
'score' => 80,
'grade' => 'A'
),
array(
'name' => 'jin',
'score' => 70,
'grade' => 'A'
),
array(
'name' => 'john',
'score' => 80,
'grade' => 'A'
),
array(
'name' => 'ben3',
'score' => 203,
'grade' => 'B3'
)
);

$titleList = array('姓名', '总分', '等级');
$fileName = '高三(3)班 7 月份考试结果';

csv_export($data, $titleList, $fileName);
