How do you access `$_list` items?
`foreach` of `false` should emit a warning. `count` of `false` should emit a warning as well.

Hello;
I have encountered this issue before and solved it.
But today it got me going around in circles again for
several hours.
The issue:
$_list = [];
if($_list = scandir( [valid directory] ) === false)
{
return // some error string;
}
Now there is code to loop through $_list
It just keeps trying to loop and nothing in the array is processed
It should have been
if( ( $_list = scandir( [valid directory] ) ) === false)
{
return // some error string;
}
Now the loop sees a valid array in $_list and can process the
$_list items
So, is it possible that an error or warning could be issues for
this type of situation?. The php interpreter seems to just be
confused.
I am used to having php poke its finger in my face when I
got it wrong, syntax wise.
Thanks for attention
JK
