Absolutely no response, this is a shame. ------------------------------------------------------------------------ [2017-04-20 09:37:09] php at grindau dot com My only working workaround looks as the follows: $cwd='/tmp'; $descriptorspec = array( 0 => array("pipe", "r"), 1 => array("pipe", "w"), 2 => array("file", "/tmp/error-output.txt", "a") ); $process = proc_open('csso '.ROOT_PATH.'/tmp/style-'.$type.'-uncritical-unoptimized.css '.ROOT_PATH.'/tmp/style-'.$type.'-uncritical.css --comments none', $descriptorspec, $pipes, '/tmp'); stream_get_contents($pipes[1]); fclose($pipes[1]); ------------------------------------------------------------------------ [2017-04-17 20:21:57] jlaustill at gmail dot com I am running into this same issue on php 5.6.30 running on Ubuntu 16.04. I'm trying to call minify(node.js library). Here's the exact call I'm making. public function minifyJsFile($source, $dest) { $result = exec('minify ' . $source . ' > ' . $dest); if ($result) { return false; } else { return filemtime($dest); } } I have been unable to find a workaround. But I'm not a php expert by any stretch. My background is c/c++/C#/javascript mainly. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
