Configurando a Connections com MySQL

Não consigo fazer os arquivos do site encontrarem o database MySQL

O modelo de connections da Hospedagem é assim:

<?

	   error_reporting(E_ALL ^ E_DEPRECATED);

	   echo time()."<br>";

	   $dbserver = "IP";

	   $dbname = "NOME DO BANCO";

	   $dbuser = "USUARIO DO BANCO";

	   $dbpassword = "SENHA DO BANCO";

	   $connect=mysql_connect($dbserver,$dbuser,$dbpassword) or die("Unable to Connect");

	   mysql_select_db($dbname) or die("Could not open the db");

	   $showtablequery="SHOW TABLES FROM $dbname";

	   $query_result=mysql_query($showtablequery);

	   while($showtablerow = mysql_fetch_array($query_result)){

	       echo $showtablerow[ 0]."<br>";

	   }

	   mysql_close($connect);

	?>

	 

	**Eu apontei assim:**

	 

	   $dbserver = "145.247.368.5";

	   $dbname = "o300651419_dados";

	   $dbuser = "o300651419_usuario";

	   $dbpassword = "senhadb";

	 

	**Então ficou assim:**

	 

	<?

	   error_reporting(E_ALL ^ E_DEPRECATED);

	  

	   echo time()."<br>";

	   $dbserver = "145.247.368.5";

	   $dbname = "o300651419_dados";

	   $dbuser = "o300651419_usuario";

	   $dbpassword = "senhadb";

	   $connect=mysql_connect($dbserver,$dbuser,$dbpassword) or die("Unable to Connect");

	   mysql_select_db($dbname) or die("Could not open the db");

	   $showtablequery="SHOW TABLES FROM $dbname";

	   $query_result=mysql_query($showtablequery);

	   while($showtablerow = mysql_fetch_array($query_result)){

	       echo $showtablerow[ 0]."<br>";

	   }

	   mysql_close($connect);

	?>

	 

	**Mas as páginas do site dão o erro:**

	 

	**Notice**: Use of undefined constant E_DEPRECATED - assumed 'E_DEPRECATED' in **/home/****o300651419****/public_html/Site/Connections/ligacao.php** on line **2**

Unable to Connect

Alguém pode me dizer onde ESTOU ERRRANDO?
