I used to code with Groovy ... I found that this 'feature' (no idea what they called it) so fun n nice (I heard they implemented this on C# too).
for example ... I want to display person neighbour name
I just type
println person?.neigbour?.name ;
it means if the neighbour is empty / blank .. it didn't display anything .
how to do this in php 5/yii?
example:
instead of typing long codes like '/>
Would it be better to type like '/>
