我正在開發(fā)在線考試系統(tǒng)，老師應(yīng)該能夠從文本文件中導(dǎo)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(gè)文件，如果該行包含問題的標(biāo)記（？），那么我可以確定它是問題部分，找到下一個(gè)問題之前的行是這個(gè)問題的答案以及旁邊有一個(gè)星號(hào)的選項(xiàng)它可以被認(rèn)為是這個(gè)循環(huán)結(jié)束時(shí)的正確答案，我需要像這樣的 JSON 數(shù)據(jù){"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(xù)$handle = fopen("test.txt", "r"); if ($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"; }
