oci_num_fields
If you want to return te number of rows without fetching all data it might by more efficient to use this code (correct me if I'm wrong):
$sql_query = 'SELECT COUNT(*) AS NUMBER_OF_ROWS FROM (' . $your_query . ')';
$stmt= oci_parse($conn, $sql_query);
oci_define_by_name($stmt, 'NUMBER_OF_ROWS', $number_of_rows);
oci_execute($stmt);
oci_fetch($stmt);
echo $number_of_rows;
oci_num_rows
(PHP 5, PECL OCI8 >= 1.1.0)
oci_num_rows — Retourne le nombre de lignes affectées durant la dernière commande Oracle
Description

( resource
$statement
)Retourne le nombre de lignes affectées durant la dernière commande Oracle.
Liste de paramètres

Exemples
Exemple #1 Exemple avec oci_num_rows()
<?php
$conn = oci_connect("scott", "tiger");
$stmt = oci_parse($conn, "create table emp2 as select * from emp");
oci_execute($stmt);
echo oci_num_rows($stmt) . " lignes insérées.<br />";
oci_free_statement($stmt);
$stmt = oci_parse($conn, "delete from emp2");
oci_execute($stmt, OCI_DEFAULT);
echo oci_num_rows($stmt) . " lignes effacées.<br />";
oci_commit($conn);
oci_free_statement($stmt);
$stmt = oci_parse($conn, "drop table emp2");
oci_execute($stmt);
oci_free_statement($stmt);
oci_close($conn);
?>
Notes
Note:
Cette fonction ne retourne pas le nombre de lignes sélectionnées. Pour les commandes de type SELECT, cette fonction va retourner le nombre de ligne qui ont été lues dans le buffer avec oci_fetch*().
Note:
Dans les versions de PHP antérieures à la version 5.0.0, vous devez utiliser la fonction ocirowcount(). Cet ancien nom est toujours utilisable : un alias a été fait vers la fonction oci_num_rows(), pour assurer la compatibilité ascendante. Toutefois, il est recommandé de ne plus l'utiliser.

hello,
here'is an example who works:
$connexion = ("name_bd","pass_db"); //set up connexion on database
$query="select * from order "; // query for the test
$parse = ociparse($connexion,$query); // parse query
ociexecute($pase); // execute the query on server (on temporary memory)
ocifetchstatement($pase,$tab_result); // the result will be fetched in the table $tab_result
echo ocirowcount($parse); // show the numbers of result
/**** and if you want to posting the results of query ***/
$count = count($tab_result);
for($i=0;$i<=$count;$i++)
{
echo $tab_result[$i]."<br>";
}
you can also do it with the function ociresult():
while(ocifetch($parse))
{
echo ociresult($parse,"[capital letter of the name of feild that you want to show on naviator]");
}
Attention : all of name of tables on oracle database are in capital letter when you use an other application for connect to it.
example :
to select the field no_client on table client, on your script of posting, you should write :
echo ociresult($parse,"NO_CLIENT");
not :
echo ociresult($parse,"no_client");
//end
Enjoy

It appears the easiest workaround if you want to get numrows without moving to the end of the result set is to use:
numrows = OCIFetchStatement(...);
OCIExecute(...);
So that the execute re-executes the query. It's horribly inefficient to query twice, but it works.

this function can be used with select statement, and also return affected number of rows.
But remember this, use this after fetch statement.
