Split string into sentences using regex

Question

I have random text stored in $sentences. Using regex, I want to split the text into sentences, see:

function splitSentences($text) {
    $re = \         


        

Answer 1

If spaces are unreliable, than you could use match on a . followed by any number of spaces, followed by a capital letter.

You can match any capital UTF-8 letter using the Unicode character property \p{Lu}.

You only need to exclude abbreviations which tend to follow own names (person names, company names, etc), since they start with a capital letter.

function splitSentences($text) {
    $re = '/                # Split sentences ending with a dot
        .+?                 # Match everything before, until we find
        (
          $ |               # the end of the string, or
          \.                # a dot
          (?

Note: This answer might not be accurate enough for your situation. I'm unable to judge that. It does address the problem as described above and is easily understandable.
