$whichwrong .= "Question Number: $questionNum || Your Answer: $userAnswers[$s][$q]\n"; 
echo $whichwrong;

顯示：在PHP不輸出換行符

The following questions were not answered correctly: Question Number: 2 || Your Answer: b Question Number: 4 || Your Answer: c Question Number: 5 || Your Answer: a Question Number: 1 || Your Answer: b Question Number: 3 || Your Answer: b Question Number: 1 || Your Answer: b Question Number: 2 || Your Answer: a Question Number: 1 || Your Answer: b Question Number: 2 || Your Answer: b

爲什麼"\n"不能正常工作？

同時這工作得很好：

$totalValue .= "Correct: {$correct}\n"; 
$totalValue .= "Wrong: {$wrong}\n";

空格在瀏覽器中，查看源文件崩潰，你會看到你的換行符，使用
元素代替硬中斷; – Orangepill

使用'\ r \ n' - '\ r'是一個回車符，'\ n'是一個新行 – crmpicco

使用nl2br插入HTML的換行符（<br />）

echo nl2br($whichwrong);

普通\n通過像正常的空格瀏覽器處理。

'致命錯誤：調用未定義的函數：n12br（）in /home/web/i/imed.com 205行上的/htdocs/test.php – Si8

nl2br！！='n12br' 1！= l – bwoebi

nl =新行。 ;）不是新的1 – Jessica

如果您正在瀏覽器中查看，您需要使用<br> - 您還可以使用nl2br()功能。如果您在控制檯中，試試\r\n
