在正则表达式搜索中包含非字母字符

Question

I have a working regex code, but it's not including the non-letter characters. How would I include those?

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

print_r($array);

Expected Results

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

Actual Results

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

I think it's because the regex code doesn't look for non-letter characters like ',!? and so on. How do I include those?

Answer 1

You need to include ' inside the character class.

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

DEMO

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