我正在開發在線考試系統，老師應該能夠從文本文件中導入問題，其中有這樣的問題what is the capital of USA?NewYork*WashingtonTexaswhat is the Capital of UAE?DUBAI*ABU DhabiAlriadh我想逐行瀏覽這個文件，如果該行包含問題的標記（？），那么我可以確定它是問題部分，找到下一個問題之前的行是這個問題的答案以及旁邊有一個星號的選項它可以被認為是這個循環結束時的正確答案，我需要像這樣的 JSON 數據{"questions": {"id": "1596805341211", "type": "Multiple Choice Single Answer", "question": "what is the capital of USA? ", "answer_options": {"1596805341213": {"marks": null, "value": "NewYork"}, "1596805363748": {"marks": null, "value": "Washington"}, "1596805372883": {"marks": "100", "value": "Texas", "selected": "Selected"}}},{"id": "1596805341212", "type": "Multiple Choice Single Answer", "question": "what is the Capital of UAE?", "answer_options": {"1596805341213": {"marks": null, "value": "DUBAI"}, "1596805363748": {"marks": null, "value": "ABU Dhabi"}, "1596805372883": {"marks": "100", "value": "Alriadh", "selected": "Selected"}}}} 我嘗試使用這段代碼，但我卡住了，我不知道如何繼續$handle = fopen("test.txt", "r"); if ($handle) { $qusetions[][]=array() ; while (($line = fgets($handle)) !== false) { if( Str::contains($line, '?')==1) { array_push($qusetions,$line); } else{ } } fclose($handle); } else { echo "Can not open"; }

$questions = [];
$i = 0;
$questionsFile = fopen(base_path('/public/questions.txt'), 'r');
while ($line = fgets($questionsFile)) {
if ($line === "\n") {
$i++;
continue;
}
if (!isset($questions['questions'][$i])){
$questions['questions'][$i] = [
'id' => rand(1596805341210, 9999999999999),
'type' => 'Multiple Choice Single Answer',
'question' => '',
'answer_options' => []
];
}
if (preg_match("/(.)+\?/", $line)) {
$questions['questions'][$i]['question'] = $line;
} else {
$answer = [
'id' => rand(1596805341210, 9999999999999),

if (preg_match("/(\*)(.)+/", $line)) {
$answer['marks'] = 100;

}
$questions['questions'][$i]['answer_options'][] = $answer;
}
}
fclose($questionsFile);
return $questions;
