I'm wondering why code like this one:

$conn = odbc_pconnect("$database", "$username", "$password");
$query = "select name from table";
$a=$query;
$table = odbc_do($conn,$query);
echo $query;
odbc_fetch_row($table);
echo odbc_result($table,1);

work but if I comment out $a=query, echo $query or thing that should not make any difference it's not. It's not a test-suite (i'll send it as fast as I would get it). There's probably bug in odbc_fetch_row as all problems that I had were connected with it.
