 Description   

Recently php moved from pcre to pcre2.

https://wiki.php.net/rfc/pcre2-migration

Seems like it is some potential to improve speed of doing regex evaluation.

Just in case wget code can be used as another example how to move to pcre2 or at lease provide on source code configuration option to choose uing pcre2

Take into account one more possible reason - ZBX-15428

Comment by Dmitry Smirnov [ 2021 Nov 19 ]

As reported in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=999920 pcre3 library is obsolete.

Your package still depends on the old, obsolete PCRE3[0] libraries
(i.e. libpcre3-dev). This has been end of life for a while now, and
upstream do not intend to fix any further bugs in it. Accordingly, I
would like to remove the pcre3 libraries from Debian, preferably in
time for the release of Bookworm.

The newer PCRE2 library was first released in 2015, and has been in
Debian since stretch. Upstream's documentation for PCRE2 is available
here: https://pcre.org/current/doc/html/

Many large projects that use PCRE have made the switch now (e.g. git,
php); it does involve some work, but we are now at the stage where
PCRE3 should not be used, particularly if it might ever be exposed to
untrusted input.

[0] Historical reasons mean that old PCRE is packaged as
pcre3 in Debian 

Please consider transition to pcre2 ASAP. Thanks.

Currently Zabbix 5 FTBFS when attempted to build against `libpcre2-dev` in Debian.
