while ($row = oci_fetch_array($stid, OCI_RETURN_NULLS+OCI_ASSOC)) {

You will most likely need to convert the string into a date using TO_DATE() , depending on the format depends on the pattern you give...
$query = "select * from daily_trades
where trdt = TO_DATE('$dt1', 'YYYY-MM-DD')";
But also if you want the dates between two dates, you should use BETWEEN .
$query = "select * from daily_trades
where trdt between TO_DATE('$dt1', 'YYYY-MM-DD')
and TO_DATE('$dt2', 'YYYY-MM-DD')";
Just make sure you get the dates the right way round (earliest to latest).

由于您必须将日期作为字符串传递，因此请在$dt1加上单'
$query = "select * from daily_trades where trdt= TO_DATE('$dt1', 'YYYY-MM-DD')";
