Beginning with PHP 4.2.0 these functions are enabled by default. You can disable the pcre functions with --without-pcre-regex . Use --with-pcre-regex=DIR to specify DIR where PCRE's include and library files are located, if not using bundled library. For older versions you have to configure and compile PHP with --with-pcre-regex[=DIR] in order to use these functions.
PHP w wersji dla systemów Windows posiada wbudowaną obsługę dla tego rozszerzenia. Nie trzeba ładować żadnych dodatkowych rozszerzeń, aby używać tych funkcji.
Informacja:
As of PHP 5.3.0 this extension cannot be disabled and is therefore always present.
It is still possible to build against an external PCRE library by using --with-pcre-regex=DIR
PCRE 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 It is possible that certain parts of the PHP documentation is outdated, in that it may not cover the newest features that PCRE provides. For a list of changes, see the » PCRE library changelog and also the following bundled PCRE history:
