Simple function to retrieve the results of an SQL statement into an array, will also cater for BLOB fields:
<?php
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;
}
?>
ibase_query
(PHP 5, PHP 7 < 7.4.0)
ibase_query — Exécute une requête sur une base iBase
Description
Exécute une requête sur une base iBase.
Liste de paramètres
-
link_identifier -
Un identifiant de connexion à InterBase. S'il est omis, la dernière connexion ouverte sera utilisée.
-
query -
Une requête InterBase.
-
bind_args -
Valeurs de retour
Si la requête émet une erreur, la fonction retournera false. Si la
requête est exécutée avec succès, et qu'il y a un jeu de résultats (même
vide), la fonction retournera un identifiant de résultat. Si la requête
est exécutée avec succès, et qu'il n'y a pas de résultat, la fonction
retournera true.
Note:
Dans les version 5.0.0 de PHP et suivantes, ibase_query() retourne le nombre d'enregistrements affectés par les requêtes
INSERT,UPDATEetDELETE. Dans un souci de compatibilité ascendante, ibase_query() retourneratruesi la requête réussi mais ne renvoie aucun enregistrement.
Erreurs / Exceptions
Si vous recevez une erreur du type "arithmetic exception, numeric overflow,
or string truncation. Cannot transliterate character between character
sets" (ceci survient lorsque vous essayez d'utiliser des
caractères accentués) avec la fonction ibase_query(),
c'est que vous devez choisir un jeu de caractères
(i.e. ISO8859_1 ou votre jeu courant).
Exemples
Exemple #1 Exemple avec ibase_query()
<?php
$host = 'localhost:/path/to/your.gdb';
$dbh = ibase_connect($host, $username, $password);
$stmt = 'SELECT * FROM tblname';
$sth = ibase_query($dbh, $stmt) or die(ibase_errmsg());
?>Voir aussi

- ibase_fetch_row() - Lit une ligne d'une base Interbase
- ibase_fetch_object() - Lit une ligne dans une base Interbase dans un objet
- ibase_free_result() - Libère un résultat iBase

Two comments on interogating system tables in Interbase or Firebird; I hope it helps.
1. if you try to build a query string to extract data from a system table (that has the form "rdb$some_name"), you should divide the "rdb$some_name" table name in your query string using the string merge operator ".".
$query = "select rdb"."$"."relation_name as TABLE_NAME from rdb"."$"."relations where rdb"."$"."system_flag=0";
2. The second thing is related to the fact that you can later use (after the call to ibase_fetch_object) as field identifier the ALIAS used in the query for the "rdb$some_name" table.
Example:
$get_table_names_query = "select rdb"."$"."relation_name as TABLE_NAME from rdb"."$"."relations where rdb"."$"."system_flag=0";
//
$res_table_names_query = ibase_query($dbconnection, $get_table_names_query);
//
while ($row_table_names = ibase_fetch_object($res_table_names_query))
{
print($row_table_names->TABLE_NAME);//alias used
}
Editor's note:
it is easier to use a backslash to protect the $-sign.
eg. "select rdb\$relation_name as TABLE_NAME from ..."

Using BLOB
Insert BLOB:
/* create blob */
$blob_id = ibase_blob_create();
/* fill blob */
ibase_blob_add($blob_id, $var_datablob);
/* close new blob */
$blob_id_str = ibase_blob_close($blob_id);
/* insert into table */
ibase_query("INSERT INTO BLOB_TABLE (ID, BLOB) VALUES (1, ?)",$blob_id_str);
Open BLOB:
/* query */
$set = ibase_query("SELECT BLOB FROM BLOB_TABLE WHERE ID = 1");
/* fetche a row */
$row = ibase_fetch_object($set);
/* open BLOB for read */
$blob_id = ibase_blob_open($row->BLOB);
/* get BLOB data */
$stringBLOB = ibase_blob_get($blob_id);
/* print BLOB */
echo $stringBLOB;
/* close new blob */
ibase_blob_close($blob_id);
/* free result */
ibase_free_result($set);

Contrary to it's description, the function does not always execute the query, unless you try fetching the results. I discovered this through the following code:
<?php
$result = ibase_query($dbh,"SELECT boniid FROM PROC_INS_OBONI_DELIV_ADDBONITM ( ? , ? , ? , ? , null , ? )", $bon_id , $plucode2 , $amount , $note , $discount);
$this->log_add(mb_convert_encoding("SELECT boniid FROM PROC_INS_OBONI_DELIV_ADDBONITM ( " . $bon_id . ", " . $plucode2 . ", " . $amount . ", " . $note . ", " . $nullparent . ", " . $discount . " )",'utf8','cp1251'));
if (!$result){
$errmsg = ibase_errmsg();
ibase_rollback($dbh);
ibase_close($dbh);
$this->log_add("Item (" . $mid . " - " . $plucode2 . ") : Error returned (" . __LINE__ . "): " . $errmsg);
return "Error sending product ( $m_name). Error message: $errmsg";
}
// item data does NOT enter the database if I don't call ibase_fetch_assoc
$row = ibase_fetch_assoc($result);
?>
This problem may be limited to FireBird 1.5 or it may not be. Either way, be wary of it.
