hook_tokens($type, $tokens, array $data = array(), array $options = array())Provide replacement values for placeholder tokens.
$type The type of token being replaced. 'node', 'user', and 'date' are common.
$tokens An array of tokens to be replaced, keyed by the literal text of the token as it appeared in the source text.
$data (optional) An associative array of objects to be used when generating replacement values.
$options (optional) A associative array of options to control the token replacement process. Common options are:
An associative array of replacement values, keyed by the original 'raw' tokens that were found in the source text. For example: $results['[node:title]'] = 'My new node';
