跳過使用php循環的幾天，幾個月和幾周之間的週末

Question

我要求用戶輸入開始日期和結束日期以生成付款時間表，並在兩個日期內循環以生成每週，每日和每月的時間表基於用戶選擇。

$f_repayment_date = "2015-01-01"; 
    $mat_date = "2015-10-01"; 
    while (strtotime($f_repayment_date) < strtotime($mat_date)) { 

     $f_repayment_date = date ("Y-m-d", strtotime("+1 month", strtotime($f_repayment_date))); 
     $count++; 


     //calculate interest on outstanding balance 


     if ($balance < $payment) { 
      $payment = $balance; 
      $interest_amount = $interest_amount ; 
      $principal = $payment - $interest_amount; 
      $due = $payment + $interest_amount; 
     } 

     $balance = $balance - $payment; 

     if ($balance < 0) { 
     $principal = $principal + $balance; 
     $interest_amount = $interest_amount; 
     $balance = 0; 
     } 
    $sql = mysql_query("insert into loan_schedule values (NULL,'$f_repayment_date','$account_number','$contract_code','$loan_product', 
    '$loan_amount','$frequency','$loan_term','$interest','$payment','$principal','$interest_amount','$balance','$due','$count','','$due','$active_loan')"); 
     } 
    } while ($balance > 0); 

Answer 1

可以使用date功能：

$weekends = array(6, 7); 
$day = date('N', strtotime('2015-10-01')); 

if (in_array($day, $weekends)) { 
    continue; // skip this day 
} 

你也應該把你的日期引號，否則你會得到2013而不是'2015-01-01'：

$f_repayment_date = '2015-01-01'; 
$mat_date = '2015-10-01';
