Question

真的难倒，我的代码不断落在下面的部分。我真的不明白为什么，任何线索都会非常感激！

    $message = "Order Number : ".$order_number."\n";
    $message .= "Coupon : ".$coupon."\n"."\n";
    $i = 0;
while (++$i) {
  if (isset($_POST['course'.$i.''])) {
    # we have a course defined, lets add it to the message.
    $message .= "Race ".$i."      : ".$_POST['course'.$i.'']."\n";
    $message .= "Date        : ".$_POST['day'.$i.'']."\n";
    $message .= "Time        : ".$_POST['hr'.$i.''].":".$_POST['min'.$i.'']."\n";
    $message .= "Race Number : ".$_POST['numb'.$i.'']."\n";
    $message .= "Race Name   : ".$_POST['name'.$i.'']."\n";
    $message .= "Horse       : ".$_POST['horse'.$i.'']."\n"."\n";

  } else {   
   break;
  }
}  
    $message .= "Copies      : ".$_POST['copies']."\n";
    $message .= "Phone       : ".$_POST['custphone']."\n";
    $message .= "Total Cost  : ".$order_amount."\n";

var_dump $ message：

    Order Number : 50638785
    Coupon : 

    Copies      : 1
    Phone       : 0123456789
    Total Cost  : 80.00

var_dump $ post：

array（13）{[＆＃34; course1＆＃34;] =＆gt; string（4）＆＃34; BRIG＆＃34; [＆＃34; DAY1＆＃34;] =＆GT; string（10）＆＃34; 16-07-2014＆＃34; [＆＃34; HR1＆＃34;] =＆GT;字符串（2）＆＃34; 15＆＃34; [＆＃34; MIN1＆＃34;] =＆GT;字符串（2）＆＃34; 30＆＃34; [＆＃34; numb1＆＃34;] =＆GT;字符串（2）＆＃34; 06＆＃34; [＆＃34; NAME1＆＃34;] =＆GT; string（14）＆＃34; Grand National＆＃34; [＆＃34; horse1＆＃34;] =＆GT;字符串（9）＆＃34;毛茛＆＃34; [＆＃34; custphone＆＃34;] =＆GT; string（11）＆＃34; 01234567898＆＃34; [＆＃34;优惠券＆＃34;] =＆GT; string（0）＆＃34;＆＃34; [＆＃34;国家＆＃34;] =＆GT; string（14）＆＃34;英国＆＃34; [＆＃34;拷贝＆＃34;] =＆GT;字符串（1）＆＃34; 1＆＃34; [＆＃34;量＆＃34;] =＆GT; string（5）＆＃34; 80.00＆＃34; [＆＃34; B1＆＃34;] =＆GT;字符串（3）＆＃34;购买＆＃34; }

这可能更好：

 $i = 0 ;    
 while(isset($_POST['course'.$i.''])) {
        # we have a course defined, lets add it to the message.
        $message .= "Race ".$i."      : ".$_POST['course'.$i.'']."\n";
        $message .= "Date        : ".$_POST['day'.$i.'']."\n";
        $message .= "Time        : ".$_POST['hr'.$i.''].":".$_POST['min'.$i.'']."\n";
        $message .= "Race Number : ".$_POST['numb'.$i.'']."\n";
        $message .= "Race Name   : ".$_POST['name'.$i.'']."\n";
        $message .= "Horse       : ".$_POST['horse'.$i.'']."\n"."\n";
        $i++;
 }

使用$ i的php“while”语句问题
