-  Beginning with PHP 4.2.0 these functions are enabled by default. You can
-  disable the pcre functions with
-  <option role="configure">--without-pcre-regex</option>. Use
-  <option role="configure">--with-pcre-regex=DIR</option> 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 <option role="configure">--with-pcre-regex[=DIR]</option> in order
-  to use these functions.
+  The PCRE extension is a core PHP extension, so it is always enabled.
+  By default, this extension is compiled using the bundled PCRE
+  library. Alternatively, an external PCRE library can be used by
+  passing in the <option role="configure">--with-pcre-regex=DIR</option>
+  configuration option where <literal>DIR</literal> is the location of
+  PCRE's include and library files.

-   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
-   <option role="configure">--with-pcre-regex=DIR</option>
+   Before PHP 5.3.0, this extension could be disabled by passing in
+   the <option role="configure">--without-pcre-regex</option>
+   configuration option.
