public Token::findWithPrefix(array $tokens, $prefix, $delimiter = ':')
Returns a list of tokens that begin with a specific prefix.
Used to extract a group of 'chained' tokens (such as [node:author:name]) from the full list of tokens found in text. For example:
1 2 3 4 5 6 7 | $data = array( 'author:name' => '[node:author:name]', 'title' => '[node:title]', 'created' => '[node:created]',);$results = Token::findWithPrefix($data, 'author');$results == array('name' => '[node:author:name]'); |
Parameters
array $tokens: A keyed array of tokens, and their original raw form in the source text.
string $prefix: A textual string to be matched at the beginning of the token.
string $delimiter: (optional) A string containing the character that separates the prefix from the rest of the token. Defaults to ':'.
Return value
array An associative array of discovered tokens, with the prefix and delimiter stripped from the key.
