Example #1 socket_strerror() example

if (false == ($socket = @socket_create(AF_INETSOCK_STREAMSOL_TCP))) {
"socket_create() failed: reason: " socket_strerror(socket_last_error()) . "\n";

if (
false == (@socket_bind($socket''80))) {
"socket_bind() failed: reason: " socket_strerror(socket_last_error($socket)) . "\n";

The expected output from the above example (assuming the script is not run with root privileges):

socket_bind() failed: reason: Permission denied
