Question

我是PHP的新手，我想在内部网络上使用amcharts的免费图表。这些图表将连接到ODBC数据库。我找到了一个解释how to connect to "mysql"的教程。但我不知道如何修改该代码，因此它将连接到我已经存在的ODBC数据库。

我编写了以下代码似乎正在运行，但我只是收到一条“正在加载数据...”的消息，而不是其他内容：

DATA.PHP文件：

<?php
// we need this so that PHP does not complain about deprecated functions
error_reporting( 0 );


// Connect to SQL
$link = odbc_connect("Driver={SQL Server Native Client 10.0};Server=XXXXXXXX;Database=XXXXXX;Trusted_Connection=Yes", "", "");
if ( !$link ) {
  die( 'Could not connect: ' . odbc_error() );
}

// Fetch the data
$query = "
  select distinct last_date,
  count(last_date) as NumberOfBIS
  from [dbo].[xxxxxx]
  group by last_date
  order by last_date";
$result = odbc_exec($link, $query);

// All good?
if ( !$result ) {
  // Nope
  $message  = 'Invalid query: ' . odbc_error() . "\n";
  $message .= 'Whole query: ' . $query;
  die( $message );
}

// Print out rows
$data = array();
while ( $row = odbc_fetch_array($result) ) {
$data[] = $row;
}
echo json_encode( $data );

// Close the connection
odbc_close( $link );
?>
