Request #66574 Allow multiple paths in php_ini_scanned_path - for feedback

Hi, See https://bugs.php.net/66574 Real use case: with Software Collections, projects are installed in /opt/<provider>/<name> So in RHSCL, PHP is installed in /opt/rh/php55 If another provider want to extend the PHP collection it will have to use another path, /opt/<otherprovider>, so it will need a way to use 2 configuration directories. The proposed path use a : separated list (or whatever the default dir separator list is) and, inspired by MANPATH syntax, empty string means default builtin value. Patch (with space changes ignored for readability): https://bugs.php.net/patch-display.php?bug_id=66574&patch=iniscan-multipath-strip.patch&revision=latest I plan to apply this minor change in 5.5. Thanks for your feedback, Remi P.S. I'm aware we probably need a more deep rework of ini management, but this is only a minor change we need for SCL.
