using sybase_fetch_field name and numeric

[Anon]

I am trying to use the name and numeric fields of the object that is returned from sybase_fetch_field. I'm using the .convention:

$iField = 0;
while ($oFields = sybase_fetch_field($iResultATable))
{
$aColumnNames[$iField] = $oFields.name;
$bColumnType[$iField] = $oFields.numeric;
$iField++;
}

But all it returns are : Objectname and Objectnumeric

Am I doing something wrong or something wrong in my syntax?
Please help.....thanx
