I actually already wrote a patch for removing alphanumeric increment and 
decrement, if you're interested: 
https://github.com/TazeTSchnitzel/php-src/tree/AlphanumericIncrement

Personally, I think the sanest solution is to increment number-looking 
strings as if they were numbers ("0" becomes 1), increment numbers 
(obviously), and throw a warning and do nothing for everything else.

Though it would be best if the $a++ behaviour matches $a += 1 and $a = 
$a + 1. So, while I'd prefer the strict approach I just mentioned, we 
should actually make it function identically to the other ways of 
incrementing.
