Bug #76663 [Nab]: fwrite(): send of X bytes failed with errno=32 Broken pipe

Edit report at https://bugs.php.net/bug.php?id=76663&edit=1 ID: 76663 Updated by: requinix@php.net Reported by: standus at post dot cz Summary: fwrite(): send of X bytes failed with errno=32 Broken pipe Status: Not a bug Type: Bug Package: *General Issues Operating System: CentOS, linux, windows PHP Version: 7.0.31 Block user comment: N Private report: N New Comment: The code you linked, which hasn't received any updates in more than four years, and was clearly written for PHP 4, does not check the return value of fwrite at all. But verifying an email account with the SMTP server is not even reliable in the first place. Require the address be entered twice by the user, validate the email address syntax is correct, and send a confirmation email with a link to your site that the user clicks so you know they received it.

I except when fwrite function return false when some uncatchable problem will happen. ------------------------------------------------------------------------ [2018-07-25 16:22:24] standus at post dot cz Other way is that in documentation for fwrite is return status if this function will fail but its not happen. ------------------------------------------------------------------------ [2018-07-25 15:45:58] requinix@php.net The only place in that code with an fwrite() is where it tries to write to a socket. Sockets break. It happens. ------------------------------------------------------------------------ [2018-07-25 15:38:41] standus at post dot cz Afted that some PHP function has some problem with DNS resolver. ------------------------------------------------------------------------ [2018-07-25 15:38:36] requinix@php.net Sorry, but your problem does not imply a bug in PHP itself.
