In the PHP manual, I find the following 'user contributed note' under "Operators".
Note that in php the ternary operator ?: has a left associativity unlike in C and C++ where it has right associativity.
You cannot write code like this (as you may have accustomed to in C/C++):
<?php $a = 2; echo ( $a == 1 ? 'one' : $a == 2 ? 'two' : $a == 3 ? 'three' : $a == 4 ? 'four' : 'other'); echo "n"; // prints 'four'
I actually try it and it really prints
four. However I could not understand the reason behind it and still feel it should print
Can someone please explain what is happening here and why it is printing 'four'?
