Question

所以这是我目前用于将特定表导出为.csv格式的代码。它到目前为止工作得很好，因为它下载文件并根据我的需要格式化数据。但是它不显示列名称

ex：目前显示

1 Jones Matt

2史密斯约翰

3 Doe Jane

我希望它显示：

ID Last_Name First_Name

1 Jones Matt

2史密斯约翰

3 Doe Jane

<?php
header("Content-type: application/csv");
header("Content-Disposition: attachment; filename=applications.csv");
header("Pragma: no-cache");
header("Expires: 0");

ini_set('display_errors',1);
$private=1;
error_reporting(E_ALL ^ E_NOTICE);

mysql_connect("localhost", "user", "pass") or die(mysql_error());
mysql_select_db("db") or die(mysql_error());

$query = "SELECT * FROM applications";
$select_c = mysql_query($query) or die(mysql_error());

while ($row = mysql_fetch_array($select_c, MYSQL_ASSOC))
{
    $result.="{$row['ID']},";
    $result.="{$row['LAST_NAME']},";
    $result.="{$row['FIRST_NAME']},";
    $result.="{$row['ORGANIZATION']},";
    $result.="{$row['TITLE']},";
    $result.="\n";

}
    echo $result;
?>

这是添加列名称的快速而又脏的方法：

<?php
header("Content-type: application/csv");
header("Content-Disposition: attachment; filename=applications.csv");
header("Pragma: no-cache");
header("Expires: 0");

ini_set('display_errors',1);
$private=1;
error_reporting(E_ALL ^ E_NOTICE);

mysql_connect("localhost", "user", "pass") or die(mysql_error());
mysql_select_db("db") or die(mysql_error());

$query = "SELECT * FROM applications";
$select_c = mysql_query($query) or die(mysql_error());

// -------------------- add the line below -----------------------------------
$result="ID,LAST_NAME,FIRST_NAME,ORGANIZATION,TITLE\n";
// -------------------- add the line above -----------------------------------

while ($row = mysql_fetch_array($select_c, MYSQL_ASSOC))
{
    $result.="{$row['ID']},";
    $result.="{$row['LAST_NAME']},";
    $result.="{$row['FIRST_NAME']},";
    $result.="{$row['ORGANIZATION']},";
    $result.="{$row['TITLE']},";
    $result.="\n";

}
    echo $result;
?>

Answer 2

只需在while周期之前添加标题行：

echo "ID,Last_Name,First_Name,ORGANIZATION,TITLE\n";

Answer 3

我假设你也想查询列名。

使用SELECT语句，您将永远不会在结果中获得列名。

在MySQL中你可以使用

SHOW COLUMNS FROM applications FROM db;

获取结果中的列名。

Answer 4

此替代实现允许您使用fputcsv来防止数据中的逗号。

<?php
header("Content-type: application/csv");
header("Content-Disposition: attachment; filename=applications.csv");
header("Pragma: no-cache");
header("Expires: 0");

ini_set('display_errors',1);
$private=1;
error_reporting(E_ALL ^ E_NOTICE);

mysql_connect("localhost", "user", "pass") or die(mysql_error());
mysql_select_db("db") or die(mysql_error());

$query = "SELECT ID, LAST_NAME, FIRST_NAME, ORGANIZATION, TITLE FROM applications";
$select_c = mysql_query($query) or die(mysql_error());
$row = mysql_fetch_array($select_c, MYSQL_ASSOC);
$fp = fopen("php://output", "w");
fputcsv($fp, array_keys($row));
do {
    fputcsv($fp, $rows);
} while ($row = mysql_fetch_array($select_c, MYSQL_ASSOC));

?>
