My PHP root is "c:\php"

My PHP.INI, this
------------
extension_dir="C:\php\extensions"


extension=php_interbase.dll

I execute sample php code, this
--------------
<?
phpinfo();
 $dbh = ibase_connect ("d:\project\klpg\database\tank.gdb", "sysdba", "masterkey");
 $stmt = 'SELECT * FROM customer';
 $sth = ibase_query ($dbh, $stmt);
 while ($row = ibase_fetch_object ($sth))
 {
  print $row->email . "\n";
 }
 ibase_close ($dbh);
?>
