An optional second parameter can be any combination of the following constants:
- OCI_BOTH - return an array with both associative and numeric indices (the same as OCI_ASSOC + OCI_NUM). This is the default behavior.
- OCI_ASSOC - return an associative array (as oci_fetch_assoc() works).
- OCI_NUM - return a numeric array, (as oci_fetch_row() works).
- OCI_RETURN_NULLS - create empty elements for the NULL fields.
- OCI_RETURN_LOBS - return the value of a LOB of the descriptor.
반환값
Returns an array with both associative and numeric indices, or FALSE if there are no more rows in the statement .

Note: Oracle returns all field names in uppercase and associative indices in the result array will be uppercased too.

while ($row = oci_fetch_array ($statement, OCI_NUM)) {
echo $row[0]."<br>";

echo $row[2]->read(100)."<br>"; //this will output first 100 bytes from LOB
}
?>
