    If you are using VirtualHosts with Apache, you might find useful the following directive:

    php_flag magic_quotes_sybase on

    Use it in any VirtualHost and it will be set locally to that VirtualHost without interfering with any global setting.
    This is an example:

    <VirtualHost 555.666.777.888>
       ServerName www.samplehost.com
       DirectoryIndex index.php index.htm
       php_flag magic_quotes_sybase on
    </VirtualHost>

    It is not possible to use interbase/firebird without initiating transactions. It seems that transactions are not automatically committed or rolled back at the end of a script, so remember to end all interbase enabled scripts with ibase_rollback() or ibase_commit().

    Worse is, that if you use ibase_pconnect (recommended), transactions survive from one request to the next. So that if you don't rollback your transaction at the end of the script, another user's request might continue the transaction that the first request opened.

    This has two implications:
    1) Clicking refresh in your browser won't make you see newer data, because you still watch data from the same transaction.
    2) Some php scripts might fail occassionally and not fail in other occasions, depending on with apache server thread and thereby which transaction they start using.

    Unfortunately, there is no such thing as
    if (ibase_intransaction()) ibase_rollback();

    so be sure that ALL your scripts end with an ibase_rollback() or ibase_commit();

    Here's an example for getting results back from stored procedure in firebird.
    The example make use of the stored procedure in Employee.gdb and the show_langs procedure.


    $host = 'localhost:X:/firebird/examples/Employee.gdb';
    $username='SYSDBA';
    $password='masterkey';

    $dbh = ibase_connect ( $host, $username, $password ) or die ("error in db connect");
    $stmt="Select * from SHOW_LANGS('SRep',4,'Italy')";
    $query = ibase_prepare($stmt);
    $rs=ibase_execute($query);
    $row = ibase_fetch_row($rs);

    echo $row[0];

    /* free result */
    ibase_free_query($query);
    ibase_free_result($rs);

    /* close db */
    ibase_close($dbh);
    ?>

    This example have 2 problems my be the autor writes it to fast but in the first case use one var for define user pass and and the use other one for call them and in secon step use comas after the ;

    $db = '/path/to/database.gdb';
    $user = 'username';
    $password = 'password';
    $res = ibase_connect($db,$dbuser,$dbpass) or die("<br>" . ibase_errmsg());

    // Query
    $sql="SELECT * FROM table;"

    For those who have problem with returning values from Stored Procedures in PHP-Interbase,  I have found a solution.   Use a select sentence like this:
    select * from sp_prodecure(param, ...)
    However, it is important that the procedure has a SUSPEND statement or else the procedure won't return any values.

    But the "message length" (see above note) bug that you encounter when you try to execute a procedure should be fixed !

    Here is a minimalistic code example. Be sure to create an user and a database in order to make it work.

    <?php
    // Minimalistic code example

    // Connection
    $db = '/path/to/database.gdb';
    $user = 'username';
    $password = 'password';
    $res = ibase_connect($db,$dbuser,$dbpass) or die("<br>" . ibase_errmsg());

    // Query
    $sql="SELECT * FROM table;"
    $result=ibase_query($res,$sql) or die(ibase_errmsg());
    while(    $row=ibase_fetch_object($result)){
            // use $row->FIELDNAME not $row->fieldname
            print $row->FIELDNAME;
    }
    ibase_free_result($result);

    // Closing
    ibase_close($res) or die("<br>" . ibase_errmsg());
    ?>

    The following code can be used when creating tables in order to get auto incrementing fields:

    <?php

    // This function generates an autoincrement field, such as MySQL AUTO_INCREMENT.
    function generate_autoincrement($tablename,$primarykey){
            // * Generator
            dbexec('CREATE GENERATOR GEN_' . $tablename . '_PK;');
            // * Trigger
            dbexec('CREATE TRIGGER INC_' . $primarykey . ' FOR ' . $tablename
                . chr(13) . 'ACTIVE BEFORE INSERT POSITION 0'
                . chr(13) . 'AS'
                . chr(13) . 'BEGIN'
                . chr(13) . 'IF (NEW.' . $primarykey . ' IS NULL) THEN'
                . chr(13) . 'NEW.' . $primarykey . '= GEN_ID(GEN_' . $tablename . '_PK, 1);'
                . chr(13) . 'END');
    }
    ?>

    Usage: <?php generate_autoincrement('table','column name'); ?>
