I see myself doing the following code for default assigment all the type on PHP
$variable = $variable ? $variable : 'default value';
I know that with 5.3 I can do
$variable = $variable ?: 'default value';
I would like to further simplify it by being able to just do
$variable ?= 'default value';
and have the variable reassigned in case it evaluates to false. Is it possible to create that assignment? Do I have to compile my own version of php to do that?
