    socket_strerror — Return a string describing a socket error

    Description

    socket_strerror(int $error_code): string

    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

    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
