如果在某些情况下存在无法分隔的点分隔符，如何使用点分隔符拆分文本

Example text:

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

I want to get output like this:

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

If I use explode() with '.' as the first parameter, itlogic.com and Mrs.leafa are separated.

try this once

$s= explode('. ',$your_sentence);

I think preg_split is a good tool for this as there may or may not be a space after the dot, right?

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

Explanation:

• \. Match a period

• (?=\s|$) Then assert a whitespace character or end of line afterwards

Regex:

(?(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
