Nope.
Keep in mind, that on strings, the [] will get or set the character of the
string at that particular location. My suspicion is that you don't give us
the real code (for where would the incrementation take place?), and you
turn the array into the string ( or number) '1' somewhere. (This often
happens when you use the return of a function (true) that works be a
reference instead of a return by accident.)

So, in the first loop, we've made $_SESSION["increment"] into a string by
accident. On the second loop, if $x = 1, that's the second position in the
string (which was not previously set). You try to set a character to an
array, so the array is converted to a string ('Array'), then it takes the
first character ('A') from that string, and put it at position 1. Hence
resulting in '1A'.

If you gave us the real code, I'd bet we'd spot where the actual overriding
on $_SESSION["increment"] takes place.
