<?php $campo == "Não Informado" ?: $campo = ''; ?>
In my theory if field equals Uninformed will return field as empty or keep value, I’m sure?

This code is very confusing, but it does one simple thing: if the value of $campo for "Não Informado", transforms the value of the field into ''.
The first thing executed in that code is $campo == "Não informado". That gives false and the expression becomes false ?: $campo = ''. From there it is a ternary operator ?: "normal", but with the second term (which executes if the first is true) blank.
A much clearer way to write the same code, also in one line, would be:
if($campo == "Não Informado") $campo = '';
In its original example, the ternary operator is being used for flow control, which is not its ideal function. This often causes confusion.
