PHP 4.0 Bug #9043 Updated: popen returns a 'Resource id #' (non null) when process cannot be created.

ID: 9043 Updated by: stas Reported By: sah@uow.edu.au Old-Status: Open Status: Closed Bug Type: *Directory/Filesystem functions Assigned To: Comments: popen runs "sh -c <your command>". This command does succeed. The fact that sh was unable to run your command should be checked by the pclose status. Moreover, popen is pretty dangerous to use in PHP, since all the I/O is buffered, and if the program exits before all the output was written, you can easily get a SIGPIPE which will kill your script.
