Previous Comments: ------------------------------------------------------------------------ [2021-02-11 11:54:16] cmb@php.net Does this still happen with any of the actively supported PHP versions[1]? [1] <https://www.php.net/supported-versions.php> ------------------------------------------------------------------------ [2015-02-03 11:55:18] yunosh@php.net I tried with 5.6 from rasmus' vagrant box, and the bug wasn't there. ------------------------------------------------------------------------ [2015-02-03 10:52:49] yohgaki@php.net I think I've seen the same issue for release version. It would be nicer add this to the bug report. ------------------------------------------------------------------------ [2015-02-03 10:36:37] yunosh@php.net Description: ------------ exec() doesn't return empty lines from execution results as empty strings, but as newline characters.
