关于php读取access数据库的问题

[weixin_42698772]

我的代码如下：
<?php
header("content-type:text/html;charset=gbk");
$odbc = "Driver={Microsoft Access Driver (*.mdb)};Dbq=".realpath("pscard.mdb");
$conn = odbc_connect($odbc, '', '', SQL_CUR_USE_ODBC);
$sql ="select * from pscard";
$query = odbc_exec($conn, $sql);
print $query."</br>";
$num = odbc_num_fields($query);
if ($num != 0)
for($i=1; $i<$num; $i++)
{
$row = odbc_fetch_row($query);
echo "->".odbc_result($query,"psname")."</br>";
}
else
print "No data";
$query->close();
?>

配置的iis服务，报错如下：
HTTP 错误 502.2 - Bad Gateway
