[PHP] ibase_connect...how to specify a port?

[James]

How do you specify a port to connect to?  I tried using 
localhost:3050  (3050 is the default port that Firebird) and that 
didn't work.

$host = 'localhost:/path/to/your.gdb' ;
$username = 'SYSDBA';
$password = 'masterkey';

   $dbh = ibase_connect ( $host , $username , $password );
