From: contact at sshilko dot com Operating system: Ubuntu 14.04.3 LTS PHP version: 7.0.4 Package: Sockets related Bug Type: Bug Bug description:fwrite returns 0 instead of FALSE when feof Description: ------------ Hi, there is an issue when detecting broken socket connections: The behavour is different between 7.0.2 and 7.0.4 According to documentation fwrite should "fwrite() returns the number of bytes written, or FALSE on error." But it returns 0 (int) instead of FALSE (bool) and generates NOTICE. Also feof() never works on 7.0.2 (MacOSX) but works on 7.0.4 on Ubuntu if (feof($fp)) { echo 'FEOF detected'; } Test script: --------------- Open 2 terminals and launch 1# php server.php 2# php client.php Then press CTRL+C on server.php terminal: https://gist.github.com/sshilko/443ae40a4d115ca8325b Expected result: ---------------- Written result bool(FALSE) Actual result: -------------- $ php server.php Dispatching...
