Please note that you can still reference a column that has a very complex name by using the curly syntax as shown in this example:
<?php
$queryStr = 'SELECT COUNT(*) FROM FOOBAR'; //Complex name!
// parse and exec...
$queryObj = oci_fetch_object($quertStmt);
echo 'Count: ' . $queryObj->{'COUNT(*)'}; //Curly syntax reference
?>
