Question

我正在为我的团队构建一个自定义查询编写器，他们可以简单地放入查询，然后将其导出到csv文件。它使用ODBC PDO驱动程序。如何提取列名称/别名？查询通常会包含以下内容：

$query = "SELECT
jcst.Loc_No,
jcst.Emp_No,
round(Sum(jcst.Amt_1), 2) AS Gross_Wages,
round(Sum(jcst.Amt_12),2) as Local_Tax,
round(sum(jcst.Amt_3+jcst.Amt_2),2) As Fica,
round(sum(jcst.Amt_4),2) as FUTA,
round(Sum(jcst.Amt_5),2) as SUTA,
round(sum(jcst.Amt_10),2) as Admin_Fee,
round(Sum(jcst.Amt_13),2) as Other_Costs
FROM Master";

我需要Loc_No，Emp_No，Gross_Wages，Local_Tax，FICA，SUTA，Admin_Fee，Other_Costs作为标题列信息。如何根据查询获取列/别名？

由于

Answer 1

$sth->setFetchMode(PDO::FETCH_ASSOC);

foreach ($sth->fetch() as $key => $value) {
    $array[] = $key;
}

var_dump($array);

对于那些想知道如何做的人来说！

Answer 2

you may try if you are expecting the display as below

$result = mysqli_fetch_array(....);
...
foreach ($result as $res)
{
echo $res['Loc_No']."<br \>";
echo $res['Emp_No']."<br \>";
echo $res['Gross_Wages']."<br \>";
echo $res['Local_Tax']."<br \>";
echo $res['FICA']."<br \>";
echo $res['SUTA']."<br \>";
echo $res['Admin_Fee']."<br \>";
echo $res['Other_Costs']."<br \>";
}
....

使用ODBC PDO从查询中获取列名称/别名
