正在制定贷款摊还计划,需要日期循环的帮助。我已经能够获得付款的时间表,但需要有关日期的帮助。请帮我解决日期循环问题。 感谢
echo '<table border="1">';
echo '<tr><th>#</th><th>PAYMENT</th><th>INTEREST</th><th>PRINCIPAL</th><th>BALANCE</th></tr>';
$start_date = '2014-12-14';
$end_date = '2015-03-12';
$count = 0;
do {
$count++;
// calculate interest on outstanding balance
$interest = $balance * $rate/100;
// what portion of payment applies to principal?
$principal = $payment - $interest;
// watch out for balance < payment
if ($balance < $payment) {
$principal = $balance;
$payment = $interest + $principal;
} // if
// reduce balance by principal paid
$balance = $balance - $principal;
// watch for rounding error that leaves a tiny balance
if ($balance < 0) {
$principal = $principal + $balance;
$interest = $interest - $balance;
$balance = 0;
} // if
echo "<tr>";
echo "<td>$count</td>";
echo "<td>" .number_format($payment, 2, ".", ",") ."</td>";
echo "<td>" .number_format($interest, 2, ".", ",") ."</td>";
echo "<td>" .number_format($principal, 2, ".", ",") ."</td>";
echo "<td>" .number_format($balance, 2, ".", ",") ."</td>";
echo "</tr>";
@$totPayment = $totPayment + $payment;
@$totInterest = $totInterest + $interest;
@$totPrincipal = $totPrincipal + $principal;
if ($payment < $interest) {
echo "</table>";
echo "<p>Payment < Interest amount - rate is too high, or payment is too low</p>";
exit;
} // if
} while ($balance > 0);
echo "<tr>";
echo "<td> </td>";
echo "<td><b>" .number_format($totPayment, 2, ".", ",") ."</b></td>";
echo "<td><b>" .number_format($totInterest, 2, ".", ",") ."</b></td>";
echo "<td><b>" .number_format($totPrincipal, 2, ".", ",") ."</b></td>";
echo "<td> </td>";
echo "</tr>";
echo "</table>";

答案 0 :(得分:3)
$timestampInOneWeek = strtotime('+1 week');
$timestampOneMonthAfter01january = strtotime('+1 month', 1419984000);
您也可以使用DateTime::add
$month_later = new DateTime('2000-01-01');
$month_later->add(new DateInterval('P1M'));
