From: yuri dot kanivetsky at gmail dot com Operating system: arch linux PHP version: 5.5.11 Package: Filesystem function related Bug Type: Bug Bug description:filesystem functions don't handle anonymous pipes correctly Description: ------------ php's filesystem functions can't handle files like /dev/fd/*, e.g.: $ php -d open_basedir= -r 'var_dump(file_get_contents($_SERVER["argv"][1]));' -- <(echo test) As opposed to other languages, including C: $ ruby -e 'p File.read ARGV[0]' <(echo test) $ perl -e 'open F, @ARGV[0]; print <F>' <(echo test) $ cat <(echo test) $ node -e 'var fs = require("fs"); fs.readFile(process.argv[1], "utf8", function(err, data) { console.log(data); })' <(echo test) Please consider explaining what prevents php from opening such files, if you don't consider it a bug.
