If there was a particular reason strip_tags removed them then the behavior should probably stay, but otherwise I think it's a (undoubtedly rare) edge case that should be fine to remove. ------------------------------------------------------------------------ [2019-08-01 21:58:48] peehaa@php.net Sorry Damien you were too fast again :-) Want to change it back to FR? ------------------------------------------------------------------------ [2019-08-01 21:57:20] peehaa@php.net This is clearly documented. https://www.php.net/manual/en/function.trim.php ------------------------------------------------------------------------ [2019-08-01 21:55:35] requinix@php.net Undocumented?
