Answer 1

function parseQuestions($str) { 
     $str = preg_replace("/\r|\n|\t/", " ", $str); // Remove line breaks and replace with spaces 

     $split_questions = preg_split("/\d+\./", $str, -1, PREG_SPLIT_NO_EMPTY); // An array containing each question and their answers as a string 
     $split_answers = array(); // Array that will contain the final arrays with questions and their answers 

     foreach($split_questions as $qkey => $q) { // Parses the question and splits it so [0] is the question and everything following are answers 
      $split_answers[$qkey] = preg_split("/[a-zA-Z]\)/", $q); 

      foreach($split_answers[$qkey] as $akey => $a) { // Loop that goes through each of the answers and trims off whitespace 
       $split_answers[$qkey][$akey] = trim($a); 
      } 
     } 

     return $split_answers; 
    } 

此函数将返回一个包含您的问题的数组。数组的索引0将成为你的问题，所有后续索引将成为答案。例如，当提供时字符串：

1. What is the first letter of the alphabet? 
A) no 
B) 17 
C) A 

2. What time is it? 
A) 7:02 
B) Night Time 
C) I don't know 
D) Hammer Time! 

该函数将返回一个数组具有以下结构：

[ 
    [ 
     "What is the first letter of the alphabet?", 
     "no", 
     "17", 
     "A" 
    ], 
    [ 
     "What time is it?", 
     "7:02", 
     "Night Time", 
     "I don't know", 
     "Hammer Time!" 
    ] 
] 

空白移除并忽略，因此不应该影响到返回的数组。

Answer 2

PHP的代码可能是这样的：

$array = [ 
'q1' => [ 
     'Ans1', 
     'Ans2' 
     ], 
'q2' => [ 
     'Ans1', 
     'Ans2' 
     ]  

];
