Question

我正在构建一个PHP页面来从Azure SQL数据库中读取数据。看起来连接和查询都有效，但我无法显示任何返回的数据。

我在网页上得到的输出是

已建立连接。声明已执行。有行。

<?php
$connectionInfo = array( "Database"=>"sitrap", "UID"=>"xxxxxx@xxxxxx", "PWD"=>"xxxxxx");
$serverName = "tcp:xxxxxx.database.windows.net,1433";
$conn = sqlsrv_connect($serverName, $connectionInfo);
if( $conn ) {
     echo "Connection established.<br />";
}else{
     echo "Connection could not be established.<br />";
     die( print_r( sqlsrv_errors(), true));
}
$sql = "SELECT time, callsign FROM reports";
$stmt = sqlsrv_query($conn, $sql);
if ( $stmt )  
{  
     echo "Statement executed.<br>\n";  
}   
else   
{  
     echo "Error in statement execution.\n";  
     die( print_r( sqlsrv_errors(), true));  
}  
if ($stmt) {
   $rows = sqlsrv_has_rows( $stmt );
   if ($rows === true)
      echo "There are rows. <br />";
   else 
      echo "There are no rows. <br />";
}
while ($row = sqlsrv_fetch_array($stmt))
{  
?>
  <tr>
    <td><?php echo $row["time"];?></td>
    <td><?php echo $row["callsign"];?></td>
  </tr>
<?php
}
sqlsrv_free_stmt( $stmt);  
sqlsrv_close( $conn);  
?>

在PHP日志文件中，我发现问题是以非字符串格式返回“time”。重新格式化时间格式时，它开始起作用。

{    
  echo "Col1: ".$row[0]->format('Y-m-d H:i:s')."\n";    
}

没有数据从PHP返回数据库
