PHP preg_split или preg_match предложения, но сохраняйте знаки препинания в Array

Question

Я ищу разбивку абзаца на предложения, а затем в строки «взорванных», но нужно сохранить пунктуации как элементы массива.

Пример текста:

$meta = 'I am looking to break this paragraph into chunks. 
     I have researched, tried and tested various combinations; however, I cannot 
     seem to make it work. Would anyone help me figure this out? 
     I thank you in advance...' 

Нужный результат будет:

Array ([0] => 
      Array ([0] => I [1] => am [2] => looking [3] => to [4] => break [5] => [6] => this [7] => paragraph [8] => into [9] => chunks [10] => .) 
     [1] =>  
      Array ([0] => I [2] => have [3] => researched [4] => , [5] => tried [...... 
      ......] [5] => figure [6] => this [7] => out [8] => ?) 
     [3] => 
      Array ([0] => I [1] => thank [2] => you [3] => in [4] => advance [5] => ...) 
    ) 

Я попытался с помощью:

$s = preg_split('/\s*[!?.]\s*/u', $meta, -1, PREG_SPLIT_NO_EMPTY); 

отделить приговоры, но в то время как это работает, то пунктуация исчезает.

Я действительно ценю помощь с созданием этого два массива уровня с пунктуацией

Вы могли бы сделать то, что вы хотите использовать preg_match:

$meta = 'I am looking to break this paragraph into chunks. 
     I have researched, tried and tested various combinations; however, I cannot 
     seem to make it work. Would anyone help me figure this out? 
     I thank you in advance...'; 

preg_match_all('/(\w+|[.;?,]+)/', $meta, $m); 
print_r($m); 

Пояснение:

/   : regex delimiter 
    (  : begin group 1 
    \w+  : 1 or more aphanumeric character <=> [a-zA-Z0-9_] 
    |  : OR 
    [.;?,]+ : 1 or more punctuation 
)   : end of group 1 
/   : regex delimiter 

Этот будет соответствовать и хранить в группе 1 evry word каждую группу символов пунктуации.

Если вы хотите быть юникода совместимы, вы могли бы использовать \p{L} для любого письма и \p{P} пунктуации:

/(\p{L}+|\p{P}+)/ 

Выход:

Array
