SimpleDebuggableConnection extends StreamConnection
in package

Standard connection to Redis servers implemented on top of PHP's streams.

The connection parameters supported by this class are:.

  • scheme: it can be either 'redis', 'tcp', 'rediss', 'tls' or 'unix'.
  • host: hostname or IP address of the server.
  • port: TCP port of the server.
  • path: path of a UNIX domain socket when scheme is 'unix'.
  • timeout: timeout to perform the connection (default is 5 seconds).
  • read_write_timeout: timeout of read / write operations.
  • async_connect: performs the connection asynchronously.
  • tcp_nodelay: enables or disables Nagle's algorithm for coalescing.
  • persistent: the connection is left intact after a GC collection.
  • ssl: context options array (see http://php.net/manual/en/context.ssl.php)
