Question

I am using this code to split my content after the first punctuation mark, retrieving the fist sentence.

$content = preg_split('/(?<=[!?.])./', $content);

How can I remove that remaining punctuation mark at the end of the splitted sentence?

Answer 1

How about:

$content = "Hello, world! What's new today? Everything's OK.";
$arr = preg_split('/[!?.] ?/', $content, -1, PREG_SPLIT_NO_EMPTY);
print_r($arr);

This splits on punctuation mark !?. followed by an optionnal space. The captured strings don’t contain leading space.

The difference with yours is that I don’t catch the punctuation.

output:

Array
(
    [0] => Hello, world
    [1] => What's new today
    [2] => Everything's OK
)
