PHP导出数据到CSV文件函数 csv_export，

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();
}

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);
