Read Carefully! Breaking changes in compare with native PHP package

1. Console version /usr/bin/php81 is installed with php81-cli subpackage, php81 doesn't include it anymore!!!

2. PEAR and PECL are available as php81-pear and php81-pecl subpackages

3. All shared modules are respresented as stand-alone subpackages and are not included with php81 package anymore.

4. No more extensions in php.ini itself!

Separate INI files for each extension are placed in /etc/php81/conf.d

They are loaded in correct order according to priority

I'm hitting a build issue, any idea if that c++11 is coming from my system or the package / phps source?

Error: Anmerkung: »std::enable_if_t« ist erst ab C++14 verfügbar

it seems something passes both -std=c++17 and -std=c++11 to libtool or something along those lines

/bin/sh /home/birdspider/.cache/paru/clone/php81/src/build-cli/libtool \
  ... -std=c++17 \
  ... -std=c++11 \

Package fails to build again, libxml error... Error available at least on php56, php80 and php81

Log : https://pastebin.com/EUfv3LTx

@jacklem thanks for fix, included to PKGBUILD

I FIXED THE ERRORS BY CHANGING THE FILES SHOWN HERE IN THE PHP SOURCE AT GITHUB https://github.com/php/php-src/commit/8a95e616b91ac0eeedba90a61e36e652919763f2

Package FAILS to build due to several similar errors in the file php.libxml.h from lines 148 to 154.

Upgraded to 8.1.24. Everything's fine. The only thing is that I still need to set values for CFLAGS and CXXFLAGS variables.
