Just had PHP7 added to my hosting account and thought I’d have a play with it. The whole site is running noticeably faster however I spotted an anomaly with “preview_text” when using the multiple form options within custom modules (using the same approach as the Tab module). Basically when I run the site using PHP7 the preview text is no longer displayed for each row (so you don’t know straightaway which item you’re editing). When I then switch back to PHP 5.6 it’s working fine so assuming it’s just something that needs to be adapted for the new version of PHP.
Obviously not a biggy but mainly wanted to flag incase you guys weren’t aware. Hopefully this can be addressed in future releases as it’d be great to take advantage of PHP7’s speed improvements!
