See https://3v4l.org/VStV6 Internally, stream_socket_get_name (https://lxr.room11.org/xref/php-src%407.1/ext/standard/streamsfuncs.c) calls php_stream_xport_get_name (https://lxr.room11.org/source/s?refs=php_stream_xport_get_name&project=php-src@7.1). The observed \0 string seems to be a returned empty C string buffer not further checked? Test script: --------------- <?php $s = stream_socket_server('unix:///tmp/demo.sock'); $c = stream_socket_client('unix:///tmp/demo.sock'); var_dump( stream_socket_get_name($s, true), stream_socket_get_name($c, false) ); Expected result: ---------------- bool(false) bool(false) Actual result: -------------- bool(false) string(1) "" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74556&edit=1
