Встановлення

The PCRE extension is a core PHP extension and is always enabled.

By default, the extension uses a bundled version of the PCRE2 library. On non-Windows systems, an external PCRE2 library can be used instead with the --with-external-pcre configuration option. The minimum supported version is 10.30. Windows builds always use the bundled library.

PCRE2's just-in-time (JIT) compilation is enabled by default. It can be disabled with the --without-pcre-jit configuration option.

Версія PHP для Windows має вбудовану підтримку цього розширення. Не потрібно додатково підключати будь-яке розширення для використання цих функцій.

PCRE2 is an active project, and as it changes, so does the PHP functionality that relies upon it. It is possible that certain parts of the PHP documentation are outdated. For a list of changes, see the » PCRE2 library changelog. The upgrade history of the bundled library is listed below:
