If abc() returns an array, is there any possible notation that
lets me access a single element?
echo abc()[0]; // I wish this were possible
...instead of having to use an intermediate variable?
$temp = abc(); // $temp is ugly
echo $temp[0];
echo current(abc());
Maybe it will be faster if you use the temp (ugly) variable than
call a method :]
The only optimizations I'm concerned with in this example are
aesthetics and my own sanity. It just looks so ugly to use a temp
variable.
In my opinion it is more clear what exactly is going on if you use a
variable.
I suppose you're right about it being clear, but to me it lacks
aesthetic value that might make it more fun. I'm thinking of Ruby or
JQuery right now, with their ability to string together objects.
Incidentally, PHP does allow me to access properties of an object
returned from a function:
echo abc()->foo;
