socket_strerror() takes as its
errno parameter the return value of one of
the socket functions, and returns the corresponding explanatory
text. This makes it a bit more pleasant to figure out why
something didn't work; for instance, instead of having to track
down a system include file to find out what '-111' means, you
just pass it to socket_strerror(), and it tells you
what happened.
P°φklad 1. socket_strerror() example <?php
if (($socket = socket_create (AF_INET, SOCK_STREAM, 0)) < 0) {
echo "socket_create() failed: reason: " . socket_strerror ($socket) . "\n";
}
if (($ret = socket_bind ($socket, '127.0.0.1', 80)) < 0) {
echo "socket_bind() failed: reason: " . socket_strerror ($ret) . "\n";
}
?> |
The expected output from the above example (assuming the script
is not run with root privileges):
bind() failed: reason: Permission denied |
