socket_strerror

Return a string describing a socket error

Description

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

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
