ibase_fetch_object
Manual should be fixed to state the default value of $flag for this function.
ibase_fetch_row
(PHP 4, PHP 5)
ibase_fetch_row — Lit une ligne d'une base Interbase
Description
array ibase_fetch_row
( resource $result_identifier
[, int $fetch_flag
] )
ibase_fetch_row() récupère une ligne de données depuis le jeu de résultats donné.
Les appels suivants à ibase_fetch_row() vont retourner la prochaine ligne dans le résultat, ou bien FALSE s'il n'y a plus de ligne.
Liste de paramètres
- result_identifier
-
Un identifiant de résultat InterBase.
- fetch_flag
-
fetch_flag est une combinaison des constantes IBASE_TEXT et IBASE_UNIXTIME. Passer IBASE_TEXT fait retourner le contenu du BLOB au lieu de l'ID du BLOB. Passer IBASE_UNIXTIME fait retourner les valeurs date/time sous forme de timestamps UNIX au lieu de chaînes formatées.
Valeurs de retour
Retourne un tableau correspondant à la ligne récupérée, ou FALSE s'il n'y a plus de ligne. Chaque colonne du résultat est stockée dans une position du tableau, en commençant à 0.

If you have a query
"select ... from table1 where ..."
and would like to know the cardinality of the result set by issuing a separate query
"select count(*) from table1 where ..."
then you might end up with an incorrect value since an insert or delete can occur between the running of these queries (unlikely, but possible).
The only way i can think of getting the correct value would be something along the lines of
<?php
$qry = "select ... from table1 where ...";
$result = ibase_query($tr, $qry) // assume $tr is a transaction
$count = 0;
while ($row[$count] = ibase_fetch_assoc($result))
$count++;
?>
then $count is the cardinality, and $row the result set.
Then you can work with the result set:
<?php
for ($i = 0; $i < $count; $i++)
{
// do something with $row[$i]
}
?>

I had some troubles with moving php application from one dbase to another. From SyBase to Interbase.
Especially with missing function "ibase_num_rows($result)".
These are functions that helped me.
<?php
...
$dbh = ibase_connect ($host, $username, $password);
...
$ar_count_queries = array();
function ibasequery($query) {
$cquery = preg_replace("/SELECT(.*?)FROM(.*?)/","SELECT COUNT(*) FROM \\2",$query);
if ($cquery != $query) {
$crow=get_object_vars( ibase_fetch_object( ibase_query( $GLOBALS["dbh"], $cquery ) ) );
}
@$res = ibase_query($GLOBALS["dbh"],$query);
if (isset($res)) {
if (isset($crow)) {
$GLOBALS["ar_count_queries"][$res] = $radcountselect["COUNT"];
}
return $res;
}
return false;
}
function ibasenumrows($result) {
return $GLOBALS["ar_count_queries"][$res];
}
function ibasefetchrow($result) {
return get_object_vars(ibase_fetch_object($result));
}
// example
$result = ibasequery("SELECT * FROM TABLE");
$numrows = ibasenumrows($result);
echo "Number of rows: $numrows.\nContent: \n";
while ($onerow = ibasefetchrow($res)) {
foreach($onerow as $key => $value) {
echo $key.": ".$value.", ";
}
echo "\n";
}
?>
