(PHP 4 >= 4.1.0, PHP 5, PHP 7)
socket_strerror — Return a string describing a socket error
说明
socket_strerror
( int $errno
) : string
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).
返回值

parameter.
范例
Example #1 socket_strerror() example
<?phpif (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
