If you want a count, you have to specifically use a count(*) query. As of PHP 5, this function is an alias to oci_num_rows, and to quote PHP.Net's documentation on oci_num_rows()
<div style="margin-left:10px; font-size: 85%;">
This function <span><i>does not</i></span> return number of rows selected!<br>
For SELECT statements this function will return the number of rows, that were<br>
fetched to the buffer with <b>oci_fetch*()</b> functions.
</div>
</p>

Further, to quote one of the users on PHP.Net's documentation on ocirowcount():
<div style="margin-left:10px; font-size: 85%;">
<span>
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.</span>
</div>
