If you have this problem:
Warning: ibase_connect(): Unable to complete network request to host "localhost"
. Failed to locate host machine. Undefined service gds_db/tcp. in C:\\wamp\\php\\ibase.php on line 5
This is because php is deployed with old client library gds32.dll.
To resolve this, update this library to Firebird latest version of fbclient.dll, of course, rename it to gds32.dll and overwrite into php dir.
Or simply don't use localhost ou 127.0.0.1, use computer name.
ibase_connect
(PHP 4, PHP 5)
ibase_connect — InterBase データベースへの接続をオープンする
説明
InterBaseサーバへの接続を確立します。
同じ引数で ibase_connect() が再度コールされた場合、 新規のリンクは作成されず、代わりに既にオープンされているリンクの リンク ID が返されます。 ibase_close() を明示的にコールしない限り、 サーバへのリンクはスクリプトの実行終了時に閉じられます。
パラメータ
- database
-
database は接続するサーバ上のデータベース ファイルへの正しいパスである必要があります。ローカルなサーバへの 接続でない場合、使用する接続プロトコルに応じてこの引数の前に' hostname:' (TCP/IP)、'//hostname/' (NetBEUI)、'hostname@' (IPX/SPX)のどれかをつける必要があります。
- username
-
ユーザ名。php.ini ディレクティブ ibase.default_user で設定します。
- password
-
username のパスワード。 php.ini ディレクティブ ibase.default_password で設定します。
- charset
-
charset はデータベースに関するデフォルトの文字セットです。
- buffers
-
buffers はサーバ側のキャッシュに確保されるデータベースバッファの数です。0 または省略された場合、サーバーはデフォルト値を用います。
- dialect
-
dialect は、接続時に実行される全ての命令に 関する SQL 方言のデフォルト値を選択し、デフォルトではクライアント ライブラリでサポートされる方言のうち、最高位のものになります。 InterBase 6 以降でのみ有効です。
- role
-
InterBase 5 以降でのみ有効です。
- sync
-
返り値
成功した場合に InterBase リンク ID、エラー時に FALSE を返します。
エラー / 例外
この関数を使用して ibase_query() をコールした後に "arithmetic exception, numeric overflow, or string truncation. Cannot transliterate character between character sets" のようなエラーが発生した場合 (たとえばアクセント記号つきの文字を使用した場合などに発生します)、 文字セットを指定する必要があります (例: ISO8859_1 あるいは現在の文字セット)。
変更履歴
| バージョン | 説明 |
|---|---|
| 4.0.0 | buffers 、dialect および role が追加されました。 |
例
例1 ibase_connect() の例
<?php
$host = 'localhost:/path/to/your.gdb';
$dbh = ibase_connect($host, $username, $password);
$stmt = 'SELECT * FROM tblname';
$sth = ibase_query($dbh, $stmt);
while ($row = ibase_fetch_object($sth)) {
echo $row->email, "\n";
}
ibase_free_result($sth);
ibase_close($dbh);
?>

Remember for different locations
of php.ini file:
..\xampp\php\php.ini
..\xampp\apache\bin\php.ini
..\xampp\php\php4\php.ini
Please do not confuse this
and know location _loaded_ *.ini-file!

With php5 on Windows i couldnt connect to a firebird database with following error :
Warning: ibase_connect(): Unable to complete network request to host "localhost"
. Failed to locate host machine. Undefined service gds_db/tcp. in C:\\wamp\\php\\ibase.php on line 5
the connect command was "$dbh = ibase_connect ("localhost:path_to_file.fdb", $username, $password);"
The solution is to insert the line
gds_db 3050/tcp #firebird Database
into the windows services file %WINDIR%\\system32\\drivers\\etc\\services

Just to update Simon's note...
Things must have been fixed since Simon wrote that note.
With PHP5 the following example works flawlessly:
$strconnect = 'localhost:/opt/firebird/examples/employee.fdb';
if (!($db=ibase_connect($strconnect, 'sysdba', 'yourpass', 'ISO8859_1', 0, 1)))
die('Could not connect: ' . ibase_errmsg());
$sql = "SELECT PO_NUMBER, ORDER_STATUS, ITEM_TYPE FROM SALES";
$cursor = ibase_query($sql);
$row_array = ibase_fetch_row($cursor);
print_r($row_array);
ibase_free_result($cursor);
ibase_close($db);
Also you CAN get away with the following connection string:
ibase_connect('/opt/firebird/examples/employee.fdb', 'sysdba', 'yourpass')

If you get a sloooow work of ibase_connect on Win2003, try to update your FireBird to version 1.5 or above, and your InterBase to version 7.1. Or move back to Win2000 :)

I found it difficult to get anything working using the current documentation.
While logic would suggest that the format in the docs should work (being based on all the
syntax of other standard database access functions) I had problem after problem. Finally I
found some comments on a newgroup that helped, and this is the result.
This is actual production code (not a mere example). It works.
Don't ask me why it is so different from the official docs.
if ( ibase_connect( $db_filespec,$db_user,$db_pass_word) )
{
$query = "SELECT c.id, c.title, c.description ";
$query .= "FROM collections c ";
$query .= "WHERE (c.id = $page_id) ";
$result = ibase_query( $query );
$row_array = ibase_fetch_row($result);
$row_fetched = !empty($row_array);
if ($row_fetched)
{
// Extract the row into variables
$collection_id = $row_array[0];
$edit_title = $row_array[1];
$edit_desc = $row_array[2];
// Standardise the record contents
$collection_id = $collection_id + 0; // force type to numeric
}
// Wrap up the database side of things
ibase_commit(); // note parenthesis but no parameters.
ibase_close; // note total lack of parenthesis and parameters !
}
You'll notice that there is no reference to a database handle in this code.
It seems to be implicit when dealing with interbase functions. Certainly, I couldn't
get the code to work when using it explicitly. This makes the documentation
very hard to work with, and any reference to a handle needs to be ignored.
Important: ibase_close doesn't work for me if I put parenthesis after it.
eg:
ibase_close; // works
ibase_close(); // fails
ibase_close($db); // fails
Note: the line "if ($row_fetched)" could be replaced with "while ($row_fetched)"
if you need to process more than one record.
All that said, Interbase is a fantastic database to work with and IMHO a much
better choice than something like PostgreSQL if you need to move up from MySQL
to something more industrial strength. Just be sure to RTFM.

If you get a message like: 'Dynamic SQL Error SQL error code = -901 feature is not supported', this may be caused by InterBASE client 6.01 accessing a server running 5.x.
Make sure the dialect value is set to '1', like the following:
ibase_connect ('localhost:/usr/db/db.gdb', 'SYSDBA', 'masterkey', 'ISO8859_1', '100', '1' ) ;
That last value is the dialect, but you need the two preceding also, do avoid errors.
