PHP Manual: Return a string describing a socket error

Description

string socket_strerror(int $error_code)

socket_strerror takes as its error_code 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

error_code: A valid socket error number, likely produced by socket_last_error.

Return Values

Returns the error message associated with the error_code 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";
}
?>
