PHP导出生成CSV文件

composer 用起来是非常方便的 所以我是依赖composer来做的包管理

1.先安装composer 自行百度一下composer安装以及使用

2.用composer下载安装office包即可

3.不多废话 直接上代码

/**
 * @param $data array  要下载的数据
 * @param $title_arr array　表头
 * @param $filename string　文件名称
 */
function export_csv($data,$title_arr,$file_name=''){
    ini_set("max_execution_time", "3600");

    $csv_data = '';

    /** 标题 */
    $nums = count($title_arr);

    for ($i = 0; $i < $nums - 1; ++$i) {
        //$csv_data .= '"' . $title_arr[$i] . '",';
        $csv_data .= $title_arr[$i] . ',';
    }
    if ($nums > 0) {
        $csv_data .= $title_arr[$nums - 1] . "\r\n";
    }

    foreach ($data as $k => $row) {
        $_tmp_csv_data = '';
        foreach ($row as $key => $r){
            $row[$key] = str_replace("\"", "\"\"", $r);

            if ( $_tmp_csv_data == '' ) {
                $_tmp_csv_data = $row[$key];
            }
            else {
                $_tmp_csv_data .= ','. $row[$key];
            }

        }

        $csv_data .= $_tmp_csv_data.$row[$nums - 1] . "\r\n";
        unset($data[$k]);
    }

    $csv_data = mb_convert_encoding($csv_data, "cp936", "UTF-8");
    $file_name = empty($file_name) ? date('Y-m-d-H-i-s', time()) : $file_name;
    // 解决IE浏览器输出中文名乱码的bug
    if(preg_match( '/MSIE/i', $_SERVER['HTTP_USER_AGENT'] )){
        $file_name = urlencode($file_name);
        $file_name = iconv('UTF-8', 'GBK//IGNORE', $file_name);
    }
    $file_name = $file_name . '.csv';
    header('Content-Type: application/download');
    header("Content-type:text/csv;");
    header("Content-Disposition:attachment;filename=" . $file_name);
    header('Cache-Control:must-revalidate,post-check=0,pre-check=0');
    header('Expires:0');
    header('Pragma:public');
    echo $csv_data;
    exit();
}
