示例1: tokenizeToDB
/**
* Method to parse input, tokenize it, and then add it to the database.
*
* @param mixed $input String or resource to use as input. A resource
* input will automatically be chunked to conserve
* memory. Strings will be chunked if longer than
* 2K in size.
* @param integer $context The context of the input. See context constants.
* @param string $lang The language of the input.
* @param string $format The format of the input.
*
* @return integer The number of tokens extracted from the input.
*
* @since 2.5
