socket_strerror
(PHP 4 >= 4.1.0, PHP 5) socket_strerror -- Return a string describing a socket error
Descriptionstring socket_strerror ( int errno ) socket_strerror() takes as its
errno parameter a socket error code as returned by
socket_last_error() 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.
Пример 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 |
