Description

代码语言:javascript

string 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.

Note: Although the error messages generated by the socket extension are in English, the system messages retrieved with this function will appear depending on the current locale (LC_MESSAGES).

Parameters

errno

A valid socket error number, likely produced by socket_last_error().

Return Values

Returns the error message associated with the errno parameter.

Examples

<?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";
}
?>
