php - Include none letter characters in regex search -

i have working regex code, it's not including non-letter characters. how include those?

$text = "i have 1 treehouse. i'm one. have 2 cats."; preg_match_all('/[\w\s]+?\bone\s?[\w\s]*?\./', $text, $array);  print_r($array); 

expected results

$array[0] = "i have 1 treehouse."; $array[1] = "i'm one"; 

actual results

$array[0] = "i have 1 treehouse."; $array[1] = "m one"; <---cuts off @ single quote 

i think it's because regex code doesn't non-letter characters ',!? , on. how include those?

you need include ' inside character class.

\b[\w'\s]+?\bone\s?[\w\s]*?\. 

demo

preg_match_all("~\b[\w'\s]+?\bone\s?[\w\s]*?\.~", $str, $matches);
