我在moodle中看到了這個功能，他們上傳 .txt 文件并解析數(shù)據(jù)并創(chuàng)建問題庫。有些問題也有三個選項(xiàng)樣本 ：-What is php?A. Php is a language.B. Php creates HTML.C. Php is fun.D. none of these.ANSWER: DWhich is YII-2?A. Framework.B. Tool.C. None of theseANSWER: A到目前為止，我已經(jīng)嘗試過解析它，但我不知道要實(shí)現(xiàn)批量上傳到底要做什么。txt_file = file_get_contents('path/to/file.txt');$rows = explode("\n", $txt_file);array_shift($rows);foreach($rows as $row => $data){}我正在嘗試獲取的數(shù)組[['question' => 'Php is a language.','options' => [ 'A' => 'Php is a language.', 'B' => 'Php creates HTML.', 'C' => 'Php is fun.', 'D' => 'none of these.' ],'answer' => 'D'],.....]示例文件：-文件代碼fbSObnlghQkqroEk4lrQ

循環(huán)匹配，從部分創(chuàng)建單個數(shù)組，
附加到更大的數(shù)組。
不需要“選項(xiàng)”，但匹配后可以從組 AE 創(chuàng)建子數(shù)組
，然后添加到單個數(shù)組。
重復(fù)下一場比賽。
