Question

示例文字：

There is an unique news in itlogic.com. I was read it when Mrs.leafa is cooking.

我想得到这样的输出：

Array (
    [0] There is an unique news in itlogic.com.
    [1] I was read it when Mrs.leafa is cooking.
)

如果我使用explode() '.'作为第一个参数，则itlogic.com和Mrs.leafa会分开。

Answer 1

我认为preg_split是一个很好的工具，因为点之后可能有或没有空格，对吧？

$array = preg_split("/\.(?=\s|$)/m", $Text);

说明：

\.匹配一段时间
(?=\s|$)然后断言空白字符或行尾

正则表达式：

(?(DEFINE)          # Construct a definition structure
  (?<punc>[!?.]+)     # Define `punc` group consisting of `.`, `?` and `!`
)                   # End of definition
\b                  # Match a word boundary position
(?>                 # Open a grouping (non-capturing) (a)
  [a-z0-9]            # Match a digit or a lower case letter
  \w*                 # And any number of word characters
  |                   # Or
  [A-Z]               # Match an upper case letter
  \w{3,}              # And word characters more than 3
  (?=                 # Followed by
    (?&punc)          # Any number of `.`, `?` and `!` characters
  )                   # End of positive lookahead
)                   # End of grouping (a)
(?&punc)            # Match any number of `.`, `?` and `!` characters
\K\B\s*             # Reset match, assert a NWB position + any number of whitespaces
