Easy one : (numbers are separated by pipe symbol)

for 
(
 putenv("num=".(int)(bool)NO); 
 getenv ("num") <= 100; 
 putenv("num=". (getenv("num") + 1))
)
 printf("%d|", getenv("num"));

Catch :

1. No PHP variables in FOR loop

2. Code is made to be C-like syntax

3. Objective-C has macro named NO which is 0.

4. PHP has strange syntax construct "define without define" :
   if interpreter finds unqualified token in code - it assumes that this token is an undefined constant and because it's value is unknown - value is taken from token name converted to a string constant. That's why NO get's interpreted as 'NO' and because all non-empty strings in PHP means true when converted to boolean - integer 1 is saved into environment variable in FOR loop initialization part. Fortunately this PHP behavior is now a deprecated feature

5. The only thing which truly reaveals that it is PHP code snippet - string concatenation operator . If PHP would have function strcat() like C does - hiding dot from the reader would make code more inseparable from a C syntax.
