3. 11.x core/lib/Drupal/Core/Utility/Token.php \Drupal\Core\Utility\Token::findWithPrefix()

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:

$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.
