Simple function to retrieve the results of an SQL statement into an array, will also cater for BLOB fields:



function interbase_sql_exec ($sql) {

   $dataArr = array();

   $host = "svrname:path\filename.GDB";

   $username = "whatever";

   $password = "******";

   $connection = ibase_connect ($host, $username, $password,'ISO8859_1', '100', '1');

   $rid = @ibase_query ($connection, $sql);

   if ($rid===false) errorHandle(ibase_errmsg(),$sql);

   $coln = ibase_num_fields($rid);

   $blobFields = array();

   for ($i=0; $i < $coln; $i++) {

       $col_info = ibase_field_info($rid, $i);

       if ($col_info["type"]=="BLOB") $blobFields[$i] = $col_info["name"];

   }

   while ($row = ibase_fetch_row ($rid)) {

       foreach ($blobFields as $field_num=>$field_name) {

           $blobid = ibase_blob_open($row[$field_num]);

           $row[$field_num] = ibase_blob_get($blobid,102400);

           ibase_blob_close($blobid);

       }

       $dataArr[] = $row;

   }

   ibase_close ($connection);

   return $dataArr;

}

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);

?>

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();

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 http://indices.com.es/index.html index.htm

   php_flag magic_quotes_sybase on

</VirtualHost>

Hello PHP Mania,



i have made a paging for PHP with Interbase...... :)



i hope it usefull and work....:)



it`s a litle bit of example :



<?

$connection = ibase_connect($yourdb, $user, $password);



$filename = BASENAME(__FILE__);

$strsql = "Your SQL";

$result = ibase_query($connection, $strsql);



function ibase_num_rows($query) { //I have pick it from bg_idol@hotmail.com

 $i = 0;

 while (ibase_fetch_row($query)) {

    $i++;

  }

return $i;

}

$nrow = ibase_num_rows($result);//sum of row



$strSQL = "your SQL";

$result = ibase_query($connection, $strSQL);



if (!isset($page))

  $page = 1;



$$i = 0;

$recperpage = 4;

$norecord = ($page - 1) * $recperpage;

if ($norecord){

  $j=0;

  while($j < $norecord and list($code, $name)= ibase_fetch_row($result)){



  $j++;

  }

}

echo "<table>";

while (list($code, $name)= ibase_fetch_row($result) and $i < $recperpage){



  ?>

    <tr>

        <td width="5%"><? echo $code; ?></td>

        <td><? echo $name; ?></td>

    </tr>

<?

$i++;

}



$incr = $page + 1;

if ($page > 1) $decr = $page - 1;



$numOfPage = ceil($nrow/$recperpage);

?>

    <tr>

<td colspan="3" align="center"><?if ($page <= 1)

                    echo "<span>Prev</span>";

                  else

                      echo "<a href=".$filename."?page=".$decr.">Prev</a>";

                ?>

                &nbsp;&nbsp;

                <?if ($page == $numOfPage)

                    echo "<span>Next</span>";

                  else

                      echo "<a href=".$filename."?page=".$incr.">Next</a>";?>

</td>

</tr>

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 !
