(PHP 5, PECL OCI8 >= 1.1.0)
oci_num_rows — 返回语句执行后受影响的行数
$stmt
)oci_num_rows() 返回语句执行后受影响的行数。
Note:
本函数并不返回 SELECT 查询出来的行数！对于 SELECT 语句本函数将返回用 oci_fetch*() 函数取到缓冲区的行数。
Example #1 oci_num_rows() 例子
<?php
echo "<pre>";
$conn = oci_connect("scott", "tiger");
$stmt = oci_parse($conn, "create table emp2 as select * from emp");
oci_execute($stmt);
echo oci_num_rows($stmt) . " rows inserted.<br />";
oci_free_statement($stmt);
$stmt = oci_parse($conn, "delete from emp2");
oci_execute($stmt, OCI_DEFAULT);
echo oci_num_rows($stmt) . " rows deleted.<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);
echo "</pre>";
?>
oci_num_rows() 在出错时返回 FALSE。
Note:
在 PHP 5.0.0 之前的版本必须使用 ocirowcount() 替代本函数。该函数名仍然可用，为向下兼容作为 oci_num_rows() 的别名。不过其已被废弃，不推荐使用。

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;

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.
