Description:
------------
This is not a bug, but a sugestion. The codes output was not what was expected... When adding a value to a string that has a value in the front, should the value just increase in the front of the string and keep the remainder of the string in tact?

Reproduce code:
---------------
<?
$a = 98;
$a += 3;
echo "<br>A = $a";
$a .= " Test";
echo "<br>String A = $a";
$a += 3;
echo "<br>Test add 3 to string A = $a";
?>

Expected result:
----------------
A = 101
String A = 101 Test
Test add 3 to string A = 104 Test

Actual result:
--------------
A = 101
String A = 101 Test
Test add 3 to string A = 104
