Description:
------------
Using IF or WHILE statements (possibly others?), the code below produces 
unexpected results.

Test script:
---------------

//Set a variable with an initial value.
$TEST="Initial";

//Set the variable to a different value, then test for it.
if($TEST="Secondary" && $TEST==="Secondary") echo "Expected result occurred.";

else echo "Expectation FAIL";

//During the ($TEST==="Secondary") condition, $TEST should match "Secondary", having just been set to "Secondary".  Instead, there $TEST is actually still "Initial".

echo "\n".$TEST;

Expected result:
----------------
$TEST should be set to "Secondary" within the IF statement and then reflect that 
within said IF statement. It does not seem to.

Script result:

Expected result occurred.
Secondary

Actual result:
--------------
What actually happens is that $TEST only becomes "Secondart" *after* the entire IF 
statement has processed.  So any following comparison with $TEST still yields its 
initial value.

Script result:

Expectation FAIL
Secondary
