Example #1 socket_strerror() example

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

if (
false == (@socket_bind($socket'127.0.0.1'80))) {
   echo 
"socket_bind() failed: reason: " socket_strerror(socket_last_error($socket)) . "\n";
}
?>

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

socket_bind() failed: reason: Permission denied
