Php 如何从一块纯文本中提取有序的问题和答案
问题也可用于纯文本。我想能够使用PHP。但是，由于我的正则表达式信息不够，我尝试使用PHP函数来实现这一点 示例纯文本：（从第12个问题开始->第15个问题，共4个问题） 12.一名47岁男子投诉上牙部分缺失。该患者的病史表明因外伤导致牙齿缺失 持续了三个月。11号和12号失踪。13、21和22是 被2/3摧毁，并用？llings恢复。咬合是正颌的。 哪种假牙结构最适合这位患者， 考虑到他的职业是讲师？A.金属烤瓷 牙桥B.塑料牙桥C.固位卡环（bugel） 带附件的可摘局部义齿D.可摘局部层流义齿 上颌义齿，E.锻造焊接金属牙桥 多面中间部分13.一名7岁男孩被诊断患有epi- 中度腮腺炎（腮腺炎）。说出这件事最复杂的地方 疾病：A.睾丸炎B.结肠炎C.皮炎D.肺炎 胆囊炎14.在预防性检查期间，一名40岁男子 出现以下变化：边缘牙龈增大， 环形，发绀，与牙齿接触时轻微出血 探查没有痛苦。用卢格尔碘染色牙龈 溶液导致粘膜呈浅棕色。使 诊断：A.慢性卡他性龈炎B.急性卡他性龈炎 C.慢性卡他性牙龈炎恶化D.慢性肥厚性牙龈炎 牙龈炎E.泛发性牙周炎15.一名4岁男孩 诊断为急性上颌化脓性骨膜炎 起源于64颗牙齿。选择最佳治疗策略： A.64颗牙齿的拔除、截骨术、药物治疗B.64颗牙齿 拔牙、抗感染药物治疗C.牙髓学 64颗牙齿的治疗，抗感染药物治疗 D.64颗牙齿的牙髓治疗，骨膜切开术 E.截骨术、抗感染药物治疗Php 如何从一块纯文本中提取有序的问题和答案,php,regex,strpos,strlen,Php,Regex,Strpos,Strlen,问题也可用于纯文本。我想能够使用PHP。但是，由于我的正则表达式信息不够，我尝试使用PHP函数来实现这一点 示例纯文本：（从第12个问题开始->第15个问题，共4个问题） 12.一名47岁男子投诉上牙部分缺失。该患者的病史表明因外伤导致牙齿缺失 持续了三个月。11号和12号失踪。13、21和22是 被2/3摧毁，并用？llings恢复。咬合是正颌的。 哪种假牙结构最适合这位患者， 考虑到他的职业是讲师？A.金属烤瓷 牙桥B.塑料牙桥C.固位卡环（bugel） 带附件的可摘局部义齿D.可摘局部层流
- 每个问题的开头都有一个问题编号
- 问题通常有5或4个选项

AB假设你的文章总是以一个数字开头，将它们分组应该是一件简单的事情，只需跟踪你当前的问题，然后搜索下一个问题。这将有助于减少误报

作为旁注，我注意到您正在丢失诸如“fl”（f/l连字）和“fi”（f/I连字）之类的字符。如果您从数据库或网页中提取这些信息，请确保您正确处理UTF-8字符。如果您一直在处理全文，您可能会通过知道始终从“1”开始来改进结果然后下一场比赛将是“2”。等等。是的，大部分第一个问题开始了。但是我用php得到的结果是不均衡的。例如，它位于问题的中间或选项不出现@miken32与regex或。更好的是，获取更正确的数据取决于输入的外观。如何删除问题内容和选项（从数组到字符串）@BobbleBobble是否可以将其打印为常规字符串？：）我试过了<代码>$makeJson=json\u encode（$questions\u answers，json\u FORCE\u OBJECT）；$toString=json_decode（$makeJson）；foreach（$toString as$ts）{echo$ts->answers[1]；}但我没有成功。如何在代码中以纯文本打印问题和选项@Miken32这是一个简单的字符串数组，你可以用它做任何你喜欢的事情
