this codesnippet:
==========
$periodCount=3;
$sum = 2*periodCount;  // missing $ at periodCount
echo "sum $sum";
==========
gives:  "sum 0" as result

I expect to get a parse error because of the unknown identifier.
This kind of typo can be #very#  hard to find.

Please remove/(make as option) these non-quoted strings.

Is there a feature (planned) to force the detection of non declared variables?

Already in the language. Use error_reporting(E_ALL) to 
develop your apps and then turn down the reporting level for 
production.

Script:
-------------------------
<?php
error_reporting(E_ALL);

$periodCount = 3; 
$sum = 2 * periodCount;  // missing $ at periodCount 
echo "sum $sum"; 
?>
-------------------------

Ouput:
-------------------------
Warning:  Use of undefined constant periodCount - assumed 'periodCount' in /home/torben/public_html/phptest/__phplist.html on line 18
sum 0  
-------------------------
