Unsupported operand types: int + string in after ( php 8 update)

[Zacks]

How are doin' folks,

When l update to PHP 8  - I get the following error: Fatal error: Uncaught TypeError: Unsupported operand types: int + string in 

 <?php //the_field( "size" );

                  $internal = get_field('internal');
                  $terrace = get_field('terrace');
                  $garden = get_field('garden');

                  $total = $internal + $terrace + $garden;

                  echo $total;

                  ?>

Sounds like one or more of those get_fields is an empty string.

Your error message points to something type-related but your code doesn't seem to be doing anything involving types.   Do you want to revise your post, or perhaps do a bit more describing and maybe even show us the error line the is being referenced in the whole message?  Unless the error is tied to the last line.   And what is this get_field function?  Something in your script that you are not showing us?

Yes it is

   $a = '';
   $b = 2;
   echo $a + $b;

with version 8, gives

Something new to us not-yet-on-8 users.

As for get_field, just what is that?  Is that V8 as well?

Could be one of those really useful functions that comes free with a framework eg

function get_field($key)
{
    return $_GET[$key];
}

Maybe the OP will fill us in.....
