Question

I have the following code where I try to assign a value to a variable and then evaluate if it’s empty:

if(!empty($user = User::find($id))){
   // do some operations on the $user
}

But I’m getting an error… Does the PHP compiler allows this in any way?

PS. I’m using PHP 5.3

Generally if a function cant find something, ie a User, then it would return false anyway – so this is what I normally do:

if($user = User::find($id))
   // do some operations on the $user
}
else
{
   // no user found 
}
