php - 正则表达式 - 匹配“（发布|发布|提交）：”从一段文字
我需要匹配 &用正则表达式替换每个出现的字符串，如下所示：
注意： 每个字符串可以位于文本内部或文本开头；在这两种情况下，正则表达式都应该匹配从起点到行尾的所有内容
- Lorem Ipsum
发布者某人于三月...\n 发布者：三月某人...\n发布三月某人...\n- Lorem Ipsum
发布者某人...\n 作者有人在...\n提交者：有人在...\n- Lorem Ipsum
提交者有人在...\n
\n表示行尾
这就是我所做的，但接缝并不总是按预期工作。
/(?:(posted|post|submitted)\s)(?:(by))(?:(.*))\s(.*)|/i
/编辑：
好的，问题是我需要在字符串的开头和中间匹配posted|post|subscribed by，以及by 仅在字符串的开头，否则它也会匹配诸如“by the way...”之类的内容
i need to match & replace with regex each occurence of string like theese:
note: each string can be inside a text OR at the beginning of the text; in both case the regex should match everything from the starting point to the end of the line
- Lorem Ipsum
Posted bySomeone on March...\n Posted by:Someone on March...\nPostedMarch by Someone...\n- Lorem Ipsum
Post bySomeone on...\n bySomeone on....\nSubmitted by:Someone on...\n- Lorem Ipsum
Submitted bySomeone on...\n
\nmean just end of line
this is what i have done, but seams to not work always as expected.
/(?:(posted|post|submitted)\s)(?:(by))(?:(.*))\s(.*)|/i
/EDIT:
ok, the problem is i need to match posted|post|submitted by both on beginning of the string and in the middle of it, and by only at the beginning of the string otherwise it will match also something like "by the way..."
