ID: 63730 User updated by: cojabo-php at cjbn dot net Reported by: cojabo-php at cjbn dot net Summary: gethostbyname() fails silently Status: Not a bug Type: Bug Package: Network related Operating System: Ubuntu LTS PHP Version: 5.3.19 Block user comment: N Private report: N New Comment: What is the reason for that failure? How do I determine this? It seems strange that the "intended behavior" would be to fail without giving the user any means whatsoever to correct the failure.
