Good article, I’m glad some poeple cover this. One thing should be mentioned though – this should definitely not be used heavily. Embedded ternary operators, and nested ternary operators are a developer’s worst nightmare – it creates unnecessarily unreadable code that is difficult to maintain. Sometimes more code is better! :)

Great article.
In the first example, I think it’s the same thing as doing :
$var_is_greater_than_two = ($var > 2);
Right ?

Hey Dave!
I don’t use ternary very often, but is really nice in spots where things need to be tidy.

I have a bit of a word of advice here on the use of ternary and collaboration. Dave addresses that in his points above, “Tips for Using Ternary Operators”.

As a rule I use ternary only if the If/Else is a ‘single line of code’ <— Yes this is variable depending on screen size. Just don't go overboard when working collaboratively or if there is a chance some-one else will inherit the code.
