Where can I read about conditionals done with “?” and “:” (colon)? [duplicate]

Answer 1

It is:

condition ? do_if_true : do_if_false

So, for example in the below, do->something() will be run.

$true = 1;
$false = 0

$true ? $do->something() : $do->nothing();

But in the below example, do->nothing() will be run.

$false ? $do->something() : $do->nothing();
