php 导出csv （通用方法）

定义通用导出方法

function export_csv($file_name,$tileArray = [],$dataArray = [])
{
    header('Content-Type: application/vnd.ms-excel');
    header('Content-Disposition: attachment;filename='.$file_name );
    header('Cache-Control: max-age=0');
    $file = fopen('php://output',"a");
    $limit = 1000;
    $calc = 0;
    foreach ($tileArray as $v){
        $tit[] = iconv('UTF-8', 'GB2312//IGNORE',$v);
    }
    fputcsv($file,$tit);
    foreach ($dataArray as $v){
        $calc++;
        if($limit == $calc){
            ob_flush();
            flush();
            $calc = 0;
        }
        foreach($v as $t){
            $tarr[] = iconv('UTF-8', 'GB2312//IGNORE',$t);
        }
        fputcsv($file,$tarr);
        unset($tarr);
    }
    unset($list);
    fclose($file);
    exit();
}

调用

public function exportList($list)
{
    // 表格标题
    $tileArray = ['昵称', '手机号', '备注','注册时间'];
    // 表格内容
    $dataArray = [];
    foreach ($list as $vo) {
        $dataArray[] = [
            '用户昵称' => $vo['nickName'],
            '用户手机号' => $vo['phone'],
            '类型' => $vo['credittype'],
            '变动数量' => $vo['num'],
            '备注' => $vo['remark'],
            '添加时间' => $vo['create_time']
        ];
    }
    // 导出csv文件
    $filename =  '用户-' . date('YmdHis');
    return export_excel($filename . '.csv', $tileArray, $dataArray);
}
