[PHP] 使用php生成下载csv文件

原理很简单,就是用php输出一个header头,可以直接让浏览器下载文件

单元格内容用英文逗号分隔, 其中为了防止乱码,汉字部分会进行一个转码操作,从utf8转为gbk

为了使单元格看起来直观一点,会增加个t ,这样就不会看的时候出现#########

比如下面这个把moveusers数组作为csv文件下载

if(isset($_REQUEST['act'])&& $_REQUEST['act']=="downloadAll") {
    $outformat = "entmove.csv";
    $title = "邮箱名,姓名,邮箱密码,搬家状态,开始时间,结束时间,邮件总数,收取数,失败数n";
    $data = "";
    foreach ($moveUsers as $b) {
        $status = iconv("utf-8", "gbk//IGNORE", $b['status_text']);
        $realName = iconv("utf-8", "gbk//IGNORE", $b['realName']);
        $data .= "{$b['account']}t,{$realName}t,{$b['password']},{$status}t,{$b['movetime']}t"
            . ",{$b['endtime']}t,{$b['totle']},{$b['successnum']},{$b['failnum']}n";
    }
    $title = iconv("utf-8", "gbk//IGNORE", $title);
    $data = $title . $data;
    header("Cache-control: private");
    header("Pragma: public");
    header('Content-type: application/x-csv');
    if (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE 5')) {
        header("Content-Disposition: inline; filename=$outformat");
    } else {
        header("Content-Disposition: attachment; filename=$outformat");
    }
    echo $data;
    exit;
}
