       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).

	      socket_strerror(3) example

	      <?php
	      if (false == ($socket = @socket_create(AF_INET, SOCK_STREAM, SOL_TCP))) {
		 echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "
";
	      }

	      if (false == (@socket_bind($socket, '127.0.0.1', 80))) {
		 echo "socket_bind() failed: reason: " . socket_strerror(socket_last_error($socket)) . "
";
	      }
	      ?>
