ibase_connect

(PHP 5, PHP 7 < 7.4.0)

ibase_connect — Öffnet eine Verbindung zu einer Datenbank

Beschreibung

ibase_connect(
    string $database = ?,
    string $username = ?,
    string $password = ?,
    string $charset = ?,
    int $buffers = ?,
    int $dialect = ?,
    string $role = ?,
    int $sync = ?
): resource

Stellt eine Verbindung zu einem Firebird/InterBase-Server her.

Wenn ibase_connect() mit den selben Argumenten erneut aufgerufen wird, wird keine neue Verbindung hergestellt, sondern die ID der bereits geöffneten Verbindung zurück gegeben. Die Verbindung zum InterBase-Server wird am Ende des jeweiligen Skripts automatisch beendet, es sei denn, es wird vorher die Funktion ibase_close() aufgerufen.

Parameter-Liste

database: Das database-Argument muss ein gültiger Pfad zu einer bestehenden Datenbank des Servers sein. Ist der DB-Server nicht lokal, muss ihm - in Abhängigkeit vom benutzten Protokoll - ein 'hostname:' (bei TCP/IP), 'hostname/port:' (TCP/IP für Interbase Server auf benutzerdefiniertem TCP Port), oder '//hostname/' (bei NetBEUI) vorangestellt werden.
username: Der Benutzername. Kann mit der ibase.default_user php.ini Direktive festgelegt werden.
password: Das Passwort für username. Kann mit der ibase.default_password php.ini Direktive festegelegt werden.
charset: charset ist der reguläre Zeichensatz der Datenbank.
buffers: Mit buffers geben sie die Anzahl der Datenbank-Cache-Buffer (serverseitig) an. Ist der Wert 0 oder nicht angegeben, benutzt der Server seine Default-Werte.
dialect: Mittels dialect bestimmen sie den Default-Wert des anzuwendenden SQL-Dialekts für alle Anweisungen während einer Datenbank-Verbindung (default ist der Client-seitig höchst verfügbare Dialekt).
role: Wirkt nur unter InterBase 5 und höher.
sync

Rückgabewerte

Gibt bei Erfolg eine Firebird/Interbase Verbindungs-ID zurück, oder false im Fehlerfall.

Fehler/Exceptions

Erhalten Sie Fehlermeldungen wie "arithmetic exception, numeric overflow, or string truncation. Cannot transliterate character between character sets" (diese treten auf, wenn Sie Zeichen mit Akzent verwenden), wenn Sie diese Funktion und ibase_query() verwenden, müssen Sie den Zeichensatz (d.h. ISO8859_1 oder Ihren aktuellen Zeichensatz) einstellen.

Beispiele

Beispiel #1 ibase_connect()-Beispiel:

<?php
$host = 'localhost:/pfad/zu/ihrer.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);
?>

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.

If you want to connect to interbase server runned on custom port (not default port 3050), you can specify it in "database" parameter in this way: 'hostname/port:' (TCP/IP with custom port).
Examples:
$dbh = ibase_connect('example.com/11099:dbalias', $username, $password);
$dbh = ibase_connect('example.com/11099:var/data/myibase.fdb', $username, $password);
$dbh = ibase_connect('example.com/11099:C:\\data\\mywinibase.fdb', $username, $password);

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.

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')

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!

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 :)
