PHP drupal_static函数代码示例

 /**
  * Adds a log entry to a global log (per-request).
  *
  * The Mollom client may perform multiple requests, and the client is able to
  * recover from certain errors. The details of each request are important for
  * support and debugging, but individual log messages for each request are too
  * much and would confuse users, especially when (false-)errors appear in
  * between.
  *
  * Therefore, the Mollom module collects all messages generated by the module
  * integration code as well as by the Mollom client class within a single
  * request, and only logs a single message when the request ends.
  *
  * This collection expects that at least one entry is logged that contains the
  * primary log message and its severity.
  *
  * @param array $entry
  *   (optional) An associative array describing the entry to add to the log.
  *   If supplied, the special keys 'message' and 'arguments' are taken over as
  *   primary log message. All other key/value pairs will be appended to the
  *   resulting log message, whereas the key denotes a label/heading and the
  *   value is var_export()ed afterwards, unless NULL.
  * @param int $severity
  *   (optional) The severity of the primary log message, as per RFC 3164.
  *   Possible values are WATCHDOG_ERROR, WATCHDOG_WARNING, etc. See watchdog()
  *   for details. Defaults to WATCHDOG_NOTICE when a 'message' is passed.
  * @param bool $reset
  *   (optional) Whether to empty the log and return its contents.
  *
  * @return array
  *   An associative array containing the log:
  *   - message: The primary log message.
  *   - arguments: An array of placeholder token replacement values for
  *     _mollom_format_string().
  *   - severity: The severity of the primary log message.
  *   - entries: A list of all $entry items that have been passed in.
  *
  * @see mollom_exit()
