No, MediaWiki is written in a subset of php5 which is forwards compatible with php7. The backwards incompatible things are by in large things no sane code would rely on (http://php.net/manual/en/migration70.incompatible.php) There are people who are using mediawiki with php7 right now without complaint. Presumably eventually we will move to needing php7, just like once we moved from php4 to php5, but thats really just a version requirement increment. Sure there may be backwards incompatible things that come up, but thats nothing new. E.g. We used to have a class named Namespace. Then php 5.3 came along and its now MWNamespace. All signs point to php7 incompatibilities to be of this form. -- Brian _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
