Question

我需要在我的Application中将db内容导出为csv文件。它正在运行。但内容并非从第一行开始。它从第40行开始。我还需要做些什么呢？

header('Content-Encoding: UTF-8');
header("Cache-Control: cache, must-revalidate");
header("Pragma: public");
header('Content-Type: text/csv, charset=UTF-8; encoding=UTF-8');
$filename = date('Y_m_d_s');
header("Content-Disposition: attachment; filename=\"".$filename.".csv\"");

if($dbResult) {
    $cnthead=0; $cntr =count($dbResult[0])-1;
    foreach($dbResult[0] as $key => $Val){ 
        echo $key;
        if($cnthead < $cntr) {
            echo ",";
            $cnthead++;
        }
    }
    echo "\n";
    foreach($dbResult as $dbRes){
        $cntcontnt=0;
        foreach($dbRes as $dbVal){ 
            echo $dbVal; 
            if($cntcontnt < $cntr) {
                echo ",";
                $cntcontnt++;
            }
        }
        echo "\n";
    }
}

$ dbResult数组如下所示，

Array
(
    [0] => Array
        (
            [Appraisee Name] => aaa R
            [Team] => Software
            [Appraisee Emp No] => -
            [Appraiser Name] => vvv A
            [Appraiser Emp No] => -
            [Reviewer Name] => sss S
            [Reviewer Emp No] => -
            [Current Appraisal Status] => start
        )

    [1] => Array
        (
            [Appraisee Name] => gan R
            [Team] => Software
            [Appraisee Emp No] => -
            [Appraiser Name] => fcv R
            [Appraiser Emp No] => -
            [Reviewer Name] => sss S
            [Reviewer Emp No] => -
            [Current Appraisal Status] => start
        ) 
)

Answer 1

我想问题从这里开始

$cntr =count($dbResult[0])-1; //so $cntr = 7;

foreach($dbResult[0] as $key => $Val){ 
    echo $key;
    if($cnthead < $cntr) {//this condition only true for first 7 loops after it will fails
        echo ",";
        $cnthead++;
    }
}

例如，$ dbResult有超过7条记录，如果你想循环$ dbResult所有记录，那么它将不会首先进入forloop。然后按以下方式更改你的代码。

我想你需要改变

$cntr =count($dbResult[0])-1;

进入

$cntr =count($dbResult)-1;

在代码中尝试此更改

感谢用户2063756，您指出了我正确的方向。我的CSV文件是从第4行开始的。只是因为我使用的是我的常量的PHP包含文件....而且这个文件在＆＃34;之前有一个空行。

WAS ＆＃34;

而不是＆＃34;

Answer 3

我在最上面的问题上有空白行。我加了 ob_end_clean（）; 写入文件之前，问题出在解决

在php中将数据导出为csv文件时出现空白行
