 ===== Proposal ===== ===== Proposal =====
  
-The following behaviour is proposed:+The proposal is: 
 +  - always treat boolean and null types as an integer, but raise a warning. 
 +  - deprecate alphanumeric increment and introduce ''str_inc()'' and ''str_dec()''. 
 + 
 +==== Operation on bool / null ====
  
 <code php> <code php>
 // booleans // booleans
-$a = false; ++$a; // bool(true) +$a = false;  
-$a = true; --$a; // bool(false)+++$a; // int(1) + warning 
 +++$a; // int(2) 
 +$a = true;  
 +--$a; // int(0) + warning 
 +--$a; // int(-1)
  
 // null values // null values
-$a = null; --$a; // null +$a = null; --$a; // int(-1) + warning 
-$a = null; ++$a; // null+$a = null; ++$a; // int(1) + warning 
 +</code>
  
-// empty strings +==== Operation on alphanumeric strings ====
-$a = ''; ++$a; // int(1)+

 // non-numeric strings // non-numeric strings
 $a = '12d9';  $a = '12d9';

 ===== Backward Incompatible Changes ===== ===== Backward Incompatible Changes =====
  
-Null no longer increments to 1. Booleans couldn't be incremented in the first place, so there should be no breaks.+Incrementing ''null'' will now raise a warning; incrementing alphanumeric strings will raise a deprecation notice.
  
 ===== Proposed PHP Version(s) ===== ===== Proposed PHP Version(s) =====
  
-**Next 5.x** +**PHP 7**
- +
-Introduce a notice for the current string increment use case. This will help developers spot their usage more easily. +
- +
-**Next major** +
- +
-Removal of string increment using ++ and --.+
