Array and string offset access syntax with curly braces is deprecated in

[NeftaliAcosta]

I upgraded to php 7.4 and I get this issue. Help me please?

Deprecated: Array and string offset access syntax with curly braces is deprecated in C:\xampp\htdocs\proyecto\vendor\abraham\twitteroauth\src\SignatureMethod.php on line 61

    public function checkSignature(Request $request, Consumer $consumer, Token $token, $signature)
    {
        $built = $this->buildSignature($request, $consumer, $token);

        // Check for zero length, although unlikely here
        if (strlen($built) == 0 || strlen($signature) == 0) {
            return false;
        }

        if (strlen($built) != strlen($signature)) {
            return false;
        }

        // Avoid a timing leak with a (hopefully) time insensitive compare
        $result = 0;
        for ($i = 0; $i < strlen($signature); $i++) {
            $result |= ord($built{$i}) ^ ord($signature{$i});
        }

        return $result == 0;
    }

This has been fixed in #788. Update to the latest version of TwitterOAuth.
