Probleme with output of function oci_fetch_all

Hi, I use PHP with Oracle and I have this code: $req="select identifiant as \"0\", name as \"1\" from TAB_USER where identifiant='abcd' and mot_passe='password'"; $conn = oci_connect('foo', 'bar', 'BASE1'); if (!$conn) {

    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);

} $stid = oci_parse($conn, $req); oci_execute($stid); $nrows = oci_fetch_all($stid, $tab2); echo "<BR>$nrows rows fetched<br>\n"; echo "<BR>tab2[0][0]=".$tab2[0][0]; It works fine in PHP-4.3.10 and give this result 1 rows fetched tab2[0][0]=abcd But it doesn't work fine in PHP-5.2.13, because it give this : 1 rows fetched tab2[0][0]= If I add this code and run it echo "<BR>print_r tab2 =<BR>"; print_r($tab2); var_dump($tab2); I get in PHP-4.3.10 print_r tab2 = Array ( [0] => Array ( [0] => abcd ) [1] => Array ( [0] => toto ) ) array(2) { [0]=> array(1) { [0]=> string(4) "abcd" } [1]=> array(1) { [0]=> string(4) "toto" } } And in PHP-5.2.13 print_r tab2 = Array ( [0] => Array ( [0] => abcd ) [1] => Array ( [0] => toto ) )* array* '0'=>

    *array*
      0=>  string  'abcd'  /(length=4)/

'1'=>

    *array*
      0=>  string  'toto'  /(length=4)/

Why there is 'O' in PHP-5.2.13 and not 0 like PHP-4.3.10 ? Thanks for any help.
