Array and string offset access syntax with curly braces is deprecated

I've just updated my php version to 7.4, and i noticed this error pops up: > Array and string offset access syntax with curly braces is deprecated here is part of my code which is triggering the above error: public function getRecordID(string $zoneID, string $type = '', string $name = ''): string { $records = $this->listRecords($zoneID, $type, $name); if (isset($records->result{0}->id)) { return $records->result{0}->id; } return false; } there are few libraries in my project which is using curly braces to get individual characters inside a string, whats the best way to change the syntax issue?
