Just to make this completely clear, in left-associative PHP
b = a==1? 4:a==2? 5:6;
is equivalent to
b = (a==1? 4:a==2)? 5:6;
NO it is not equal. Either '==' has higher precedence OR '?:' has.

Known bug, the associativity of the ternary operator has been
broken since ages in the engine. It's on the "won't be
fixed" sheet, because of BC concerns.
- Sasch
Few minutes ago I found the following behaviour somehow wierd for me :
Prints :
a[1]b[5]
Similar C program :
main()
{
int a,b;
a = 1;
b = a==1? 4:a==2? 5:6;
printf("a[%d]b[%d]\n", a, b);
}
Prints :
a[1]b[4]

I think that the behavior of the C program is the right
