Since PHP 7.4 curly braces method to get individual characters inside a string has been deprecated.
All apps generated by scriptcase with name ending with _json.php contains this depracted syntax and the apache error_log is flooded with messages like this:
[proxy_fcgi:error] [pid 1384232:tid 140637496145664] [client 192.168.71.66:45894] AH01071: Got error 'PHP message: PHP Deprecated: Array and string offset access syntax with curly braces is deprecated in /var/www/html/xxxx_json.php
Please fix this.
Thanks
