Read Carefully! Breaking changes in compare with native PHP package

Console version /usr/bin/php56 is installed with php56-cli subpackage, php56 doesn't include it anymore!!!

PEAR and PECL are available as php56-pear and php56-pecl subpackages

All shared modules are respresented as stand-alone subpackages and are not included with php56 package anymore.

No more extensions in php.ini itself!

Separate INI files for each extension are placed in /etc/php56/conf.d

They are loaded in correct order according to priority

PHP 5.6 will stop getting security updates in January 2019. Consider upgrading to PHP 7 now

PLEASE READ : For those who are getting "unknown public key" errors, this is NOT caused by this package. It means GPG is not configured to fetch public keys automatically (which is normal by default)

Please read the instructions at https://wiki.archlinux.org/index.php/Makepkg#Signature_checking

The easiest way to overcome this is to manually import the keys from a keyserver :

$ gpg --keyserver hkp://hkps.pool.sks-keyservers.net:80 --recv-keys C2BF0BC433CFC8B3 FE857D9A90D90EC1

foxxx and I have been working together and this package can now be installed along PHP 7 from the official repos. Everything has been moved into separate directories : Config : /etc/php56 Extensions : /usr/lib/php56/modules Binaries : /usr/bin/php56, /usr/bin/php56-cgi, /usr/bin/phar56, etc. If you were previously using this as a replacement for php7, you'll have to adjust the new configuration files in /etc/php56/ to reflect the current ones in /etc/php/. Apache module (provided by php56-apache) also has a specific configuration and CAN NOT cohabit with php7_module. Use php-fpm, fcgi or cgi if you need both versions. The apache module is installed as libphp56.so, so you should use the following lines your httpd.conf : # Load php 5.6 module LoadModule php5_module modules/libphp56.so # Use it for .php extensions Include conf/extra/php56_module.conf Please let me know if you encounter any problem or have a suggestion.

@severach solution is worked, but the patch is failed on mine, I will attach my fixed patch file after edit the file manually

to summary add CFLAGS parameter with "-std=gnu17" on PKGBUILD create patch file with text below, and add the file in PKGBUILD

Got this to compile in gcc 15. Add -std=gnu17 to CFLAGS. Apply this patch. 2 test failures.

libxml2 2.13.6-2 removes /usr/bin/xml2-config which broke this package (and many others) I've working on this from github libarchive - use pkg-config to find libxml2 and with the current acinclude.m4 in the php-5.6.40 source.

NOTE: what the gods taketh away, the gods giveth back sometimes. libxml2 2.13.6-3 restores /usr/bin/xml2-config, so this builds again. Keep the previous message (below) in mind, because just as they giveth, they can taketh back again.

You will likely need to create a patch from Fix GH-14834: Error installing PHP when --with-pear is used to patch ext/xml/compat.c due to API changes in libxml2 between version 2.12 and 2.13. (you can omit the .phpt test from that commit)

If xml2-config is removed again, it looks like we can simply rename configure.in to configure.ac and mkdir m4 and add AC_CONFIG_MACRO_DIRS([m4]) (nit but should do it), then rm configure ltmain.sh aclocal.m4 and then after applying all patches in prepare(), just call autoreconf -i to regenerate the files before calling ./configure. I'm not an autotools expert, so converting the acinclude.m4 to use pkg-conf in the PHP_SETUP_LIBXML section is taking a bit of reading.

@jepg92 Thank you very much for the information. Fixed both "php56" and "php74" builds here.

@kasugano solution from @Zeph in php72 package works for me

Applied @severach patch, thanks

I found the problem. It's a bug in php, not autoconf, found with some gentle prodding from Redhat. The new autoconf code just exposed it. It's the same as the first patch but at the source.
