atchi meaning in english

outside a character class, a dot in the pattern matches any one character in the subject, including a non-printing character, but not (by default) newline. if the pcre_dotall option is set, then dots match newlines as well. the han- dling of dot is entirely independent of the handling of cir- cumflex and dollar, the only relationship being that they both involve newline characters. dot has no special meaning in a character class.
so, while both \d + and \d+? are prepared to adjust the number of digits they match in order to make the rest of the pattern match, (? \d+) can only match an entire sequence of digits.
