Question

在我的代码中，我需要保留CSV导出中mysql表中每个字段中的所有逗号...

为此，我在所有字段中都使用了双引号。这段代码完全在Linux系统中运行。在Windows中运行相同的代码时，双引号也会显示在导出的CSV文件中。这有什么问题？谁能告诉我为什么会这样？

    function  arrayToCSV($array, $header_row = true, $col_sep = ",", $row_sep = "\n", $qut = '"',$pgeTyp ="")
    {
    /*col_sep =htmlentities($col_sep);
    $row_sep =htmlentities($row_sep);
    $qut =htmlentities($qut);*/
    if (!is_array($array) or !is_array($array[0])) return false;
    //Header row.
    if ($header_row)
    {
    foreach ($array[0] as $key => $val)
    {
    //Escaping quotes.
    $key = str_replace($qut, "$qut$qut", $key);
    $output .= $col_sep.$qut.$key.$qut;
    }
    $output = substr($output, 1)."\n".$row_sep;
    }
    //Data rows.
    foreach ($array as $key => $val)
    {
    $tmp = '';

    foreach ($val as $cell_key => $cell_val)
    {  
    if($pgeTyp!="twitter" && $pagTyp!="jigsaw" && $pgeTyp=="")
    $timeValue = @checkTimeStamp($cell_val);
    else  $timeValue = '';
    if($timeValue=="True")
    {
    $cell_val = str_replace($qut, "$qut$qut", convert_time_zone($cell_val,'d-M-y h:i:s'));
    }
    else
    {
    $cell_val = str_replace($qut, "$qut$qut", $cell_val);
    }

    $tmp .= $col_sep.$qut.$cell_val.$qut;
    }
    $output .= substr($tmp, 1).$row_sep;
    }
    return $output;
    }

函数调用是，

$dbResult1[] =array('url_twitter_userid' => $selecttwittermainFtch['url_twitter_userid'],'url_tweet_name' => "$url_tweet_name",'url_twitter_uname' => "$url_twitter_uname",'url_twitter_url' => $selecttwittermainFtch['url_twitter_url'],'url_twitter_location' => "$url_twitter_location",'url_twitter_followers' => $selecttwittermainFtch['url_twitter_followers'],'url_twitter_following' => $selecttwittermainFtch['url_twitter_following'],'url_modified_on' => $modifiedon);   
echo arrayToCSV($dbResult1, true, ", ", "\n",  '','twitter');

试试这个：

function sqlQueryToCSV($filename, $query)
{
    $result = mysql_query($query);
    $num_fields = mysql_num_fields($result);
    $headers = array();
    for ($i = 0; $i < $num_fields; $i++) {
            $headers[] = mysql_field_name($result , $i);
    }
    $fp = fopen(mysql_real_escape_string(getcwd().'\\'.$filename), 'w');
    if ($fp) {
 fputcsv($fp, $headers);
 while ($row = mysql_fetch_array($result)) {
     $arrayValues = array();
     foreach ($headers as $header)
     {
         $arrayValues[] = $row[$header];
     }
     fputcsv($fp, $arrayValues);
 }
    }
    fclose($fp);
}

当您在Windows中使用任何程序（猜测Excel）打开它时，您应该能够指定用于分隔/环绕字段的字符。它可能只是假设您只是想使用逗号分隔而忽略围绕它们的双引号。
