How to exclude a substring from a string in PHP?

Question

PHP

The following line comes in response from API.YouTube:

Описание видео\nПодробное описание работы: https://site.ru/xxx/ccc/

I somehow need to split the string by "\n", merge into one and exclude everything that comes after http.* It should turn out:
Описание видео. Подробное описание работы
Something I'm dumb. And str_replace and preg_replace and explode tried...

Answer 1

.*:\s

$text = 'Описание видео\nПодробное описание работы: https://site.ru/xxx/ccc/';
preg_match('/.*:\s/', $text, $matches);
$result = trim(str_replace('\n', '. ', $matches[0]));
