Question

这是我从数据库中提取数据到csv文件的代码。它工作正常，但现在我把它放在数据有地址的程序中，因此有逗号（，），我在打印时遇到问题。

这就是它的样子：

Name        Address1         Address2         City          Email
Name1       123 Mcarthur     San Juan City    12 Jones      Manila

应该是这样的：

Name        Address1                       Address2         City          Email     
Name1    123 Mcarthur, San Juan City   12 Jones, Manila     Manila      sample@yahoo.com

城市和电子邮件被推送到另一列。我搜索了互联网，但我看到的只是用逗号（，）来表示的数据。

另外，php中的警告和错误消息也在csv文件中导出。我没有那么多问题，因为一旦我解决这个问题，我认为不会有任何警告。

然后这是我的代码：

        if(isset($_POST['csvextract'])){
        $name = "sample";
        $file = $name.".csv";

            $con = mysql_connect("localhost", "root");
            if(!$con){
                 echo "Error connection";
                     }

             $select_db = mysql_select_db('outbound', $con);
             if(!$select_db){
                 echo "Error to select database";
                    }
            mysql_set_charset("utf8", $con);

             header("Content-type: text/csv; charset=UTF-8");
             header('Content-disposition: attachment; filename='.basename($file)); 

           $myquery = mysql_query("SELECT * FROM temp");

        //While loop to fetch the records
        $contents = "Name, Company, Address1, Address2, City, Province, Postal Code, Contact No, Email, Commodity, Type, Weight, Length, Width, Height, Decreased Value, Special Instruction, Shipping Reference, Payment Method, Package No, Tracking No\n";
        while($row = mysql_fetch_array($myquery))
        {
            $contents.=$row['0'].",";
            $contents.=$row['1'].",";
            $contents.=$row['2'].",";
            $contents.=$row['3'].",";
            $contents.=$row['4'].",";
            $contents.=$row['5'].",";
            $contents.=$row['6'].",";
            $contents.=$row['7'].",";
            $contents.=$row['8'].",";
            $contents.=$row['9'].",";
            $contents.=$row['10'].",";
            $contents.=$row['11'].",";
            $contents.=$row['12'].",";
            $contents.=$row['13'].",";
            $contents.=$row['14'].",";
            $contents.=$row['15'].",";
            $contents.=$row['16'].",";
            $contents.=$row['17'].",";
            $contents.=$row['18'].",";
            $contents.=$row['19'].",";
            $contents.=$row['20'].",";
            $contents.=$row['21']."\n"; 
        }

        $contents_final = chr(255).chr(254).mb_convert_encoding($contents, "UTF-16LE","UTF-8");
        print $contents_final;
        }

Answer 1

使用此：

echo "Name, Company, Address1, Address2, City, Province, Postal Code, Contact No, Email, Commodity, Type, Weight, Length, Width, Height, Decreased Value, Special Instruction, Shipping Reference, Payment Method, Package No, Tracking No\n";
while ($row = mysql_fetch_row($myquery)) {
    fputcsv(STDOUT, $row);
}

Answer 2

我不确定你是否已经开始工作了。但是我对你的代码做了一些改动。

以下是代码：

if (isset($_POST['csvextract'])) {
$name = "sample";
$file = $name . ".csv";
$delimiter = ',';

$con = mysql_connect("localhost", "root");
if (!$con) {
    echo "Error connection";
    exit;
}

$select_db = mysql_select_db('outbound', $con);
if (!$select_db) {
    echo "Error to select database";
    exit;
}
mysql_set_charset("utf8", $con);

header("Content-type: text/csv; charset=UTF-8");
header('Content-disposition: attachment; filename=' . basename($file));

$myquery = mysql_query("SELECT * FROM temp");

//While loop to fetch the records
$contents = "Name, Company, Address1, Address2, City, Province, Postal Code, Contact No, Email, Commodity, Type, Weight, Length, Width, Height, Decreased Value, Special Instruction, Shipping Reference, Payment Method, Package No, Tracking No\n";
while ($row = mysql_fetch_array($myquery)) {

    for ($i = 0; $i < 22; $i++) {
        if (false === strpos($row[$i], $delimiter)) {
            $contents .= '"' . $row[$i] . '"';
        } else {
            $contents.=$row[$i];
        }
        if ($i === 21) {
            $contents .= "\n";
        } else {
            $contents .= $delimiter;
        }
    }
}

$contents_final = chr(255) . chr(254) . mb_convert_encoding($contents, "UTF-16LE", "UTF-8");
print $contents_final;
}

我改为跟随。

我在脚本的顶部添加了一个分隔符变量。通过这个你可以在分隔符之间轻松切换，所以如果它从，改为;你可以通过编辑1行来做到这一点。
而不是我使用for循环的所有行，因为每个表只是一个数字。
添加一个检查以查看字符串中是否包含分隔符，如果是，则将qoutes放在其周围
检查$i是否为21，因为我们需要转到新行。
当没有数据库连接或没有数据库可以选择时添加退出

如果这不起作用，请告诉我我会修复它。请注意，我没有尝试过这段代码。
