Previous Comments: ------------------------------------------------------------------------ [2016-08-20 00:54:26] PeterJCLaw at gmail dot com Description: ------------ Environment variables with hyphens in their names (e.g: getenv('A-B')) are lost when proc_open creates a child process (other process launching functions untested). Given that these appear to be valid (they're supported by 'env' on Ubuntu) and *worked under PHP 5* this seems to be a regression.
