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);

?>
