I got this error while working on a php project

Can't use method return value in write context

On this line of code.

<?php

$x = ( emtpy( get_something() ) ) ? get_something() : '';

I was searching for a good answer and found this stackoverflow post

Apparently PHP versions before 5.5 didn't support references to temporary values returned from functions.

Solution 1:

Store the returned value in a variable before testing it.

<?php

$y = get_something();
$x = ( emtpy( $y ) ) ? $y : '';

Solution 2:

Since empty is just an alias for !isset($x) || !$x. We'll just use ! operator.

<?php

$x = ( ! get_something() ) ? get_something() : '';

I will just leave it here as a note to self.
