获取数组mysql数据库php

I am trying to fetch data from database, but something is not working.

This is my code:

<?php

$koppla = mysql_connect("localhost","admin","","test");



// Check connection


if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }


    $get = mysql_query($koppla,SELECT * FROM 123);

while ($test = mysql_fetch_array($get))
{
    echo $test['tid'];
}

mysql_close($koppla);
?> `<?php

$koppla = mysql_connect("localhost","admin","","test");



// Check connection


if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }


    $get = mysql_query($koppla,SELECT * FROM 123);

while ($test = mysql_fetch_array($get))
{
    echo $test['tid'];
}

mysql_close($koppla);
?>

I am getting the following error while trying to fetch an array from a MySQL database. What is wrong?

Parse error: syntax error, unexpected '123' (T_LNUMBER) in C:\wamp\www\test.php on line 16
