PHP-8.0 SM plugins (quicksave) (calander file backend)

OS FreeBSD-13.0

I am migrating SM from one host to another.  The new host runs php80.  The old
runs php73.  I am using the FreeBSD port for SM on FreeBSD-13.0.

There is a plugin that I installed many years ago called quicksave. I cannot
find this in the prepackaged SM plugin ports.  The version I found on the SM
website dates from 2010.

The existing plugin gives this error when squirrelmail is opened:

[Thu Apr 14 11:05:10.097504 2022] [php:error] [pid 92477] [client
216.185.71.41:46251] PHP Fatal error:  Array and string offset access syntax
with curly braces is no longer supported in
/usr/local/www/squirrelmail/plugins/quicksave/login_functions.php on line 308,
referer: https://webmail-1.hamilton.harte-lyne.ca/src/left_main.php

The code for this is:

306   for ($i = 0; $i < $length; $i++)
307   {
308      $temp[$i] = ord($value{$i});
309      $temp2[$i] = isset($value{($i + 1)}) ? ord($value{($i + 1)}) : 0;
310      //temp[$i] = uniord($value{$i});
311      //temp2[$i] = isset($value{($i + 1)}) ? uniord($value{($i + 1)}) : 0;
312   }



I also have run into this error which is unrelated to quicksave but which I
could use some help with.  The calander file backend is a ported plugin but it
seems not to work.

The code appears to be:

475  function getCalendarFromFile($file)
476  {
477
478     // read the file all at once
479     //
480     $fileContents = file($file);
481
482
483     return Calendar::getCalendarFromICal($fileContents);
484
485 }


Any help getting this sorted out is appreciated.
