public function Data::flatten in Translation Management Tool 8

Converts a nested data array into a flattened structure with a combined key.

This function can be used by translators to help with the data conversion.

Nested keys will be joined together using a colon, so for example $data['key1']['key2']['key3'] will be converted into $flattened_data['key1][key2][key3'].

Parameters

array $data: The nested array structure that should be flattened.

string $prefix: Internal use only, indicates the current key prefix when recursing into the data array.

array $label: Label for the data.

Return value

array The flattened data array.
