private function FootnotesFilter::findFootnote in Footnotes 8.2

Search the $store_matches array for footnote text that matches.

Note: This does a linear search on the $store_matches array. For a large list of footnotes it would be more efficient to maintain a separate array with the footnote content as key, in order to do a hash lookup at this stage. Since you typically only have a handful of footnotes, this simple search is assumed to be more efficient, but was not tested.

Parameters

string $text: The footnote text.

array $store_matches: The matches array.

Return value

string|false The value of the existing footnote, FALSE otherwise.
