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. It is recommended to use PCRE 8.10 or newer;
|
|
as of PHP 7.3.0, PCRE2 is required.
|
|
</para>
|
|
<para>
|
|
PCRE's just-in-time compilation is supported by default, which
|
|
can be disabled with the <option role="configure">--without-pcre-jit</option>
|
|
configuration option as of PHP 7.0.12.

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of the PHP documentation is outdated, in that it may not cover the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
|
|
<link xlink:href="&url.pcre.changelog;">PCRE library changelog</link>
