如何在PHP中使用Oracle数据库(5)

利用ORA列出全部数据表'email_info'中的数据

下面，我们将逐条读出数据库的内容，并以html表格形式显示'email_info'数据表中的数据  

相关PHP代码:

PutEnv("ORACLE_SID=ORASID");

$connection = Ora_Logon ("username","password");
if ($connection == false){
  echo Ora_ErrorCode($connection).": ".Ora_Error($connection)."
";
  exit;
}

$cursor = Ora_Open ($connection);
if ($cursor == false){
  echo Ora_ErrorCode($connection).": ".Ora_Error($connection)."
";
  exit;
}    

$query = "select * from email_info";
$result = Ora_Parse ($cursor, $query);
if ($result == false){
  echo Ora_ErrorCode($cursor).": ".Ora_Error($cursor)."
";
  exit;  
}

$result = Ora_Exec ($cursor);
if ($result == false){
  echo Ora_ErrorCode($cursor).": ".Ora_Error($cursor)."
";
  exit;
}

echo " ";
echo "  Full Name Email Address  
";

while (Ora_Fetch_Into ($cursor, &$values)){
  $name = $values[0];
  $email = $values[1];

  echo "  $name $email  
";
}

echo " ";

Ora_Close ($cursor);
Ora_Logoff ($connection);

?>  

程序运行的浏览效果如下所示:

    
姓名 Email 地址  
春花 [e-mail]  
秋月 [e-mail]
