Example #1 socket_strerror() example
<?php
if ( false == ( $socket = @ socket_create ( AF_INET , SOCK_STREAM , SOL_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
