In php you can do stuff like this:
$string = "abcde";
$a = $string[0];
But its not working in zephir. What is best way to select first letter in string ? substr(string,0,1) or something else ?
Also it would be great if optimizer could figure out when we comparing string[0] to another string and allow it.
As you can see this aproach works well
alphabet[(int) idx]
Weird. So it should just work ? If i use alphabet[0] then i got error about Cannot use a scalar value as an array in in php user land(it's compile fine).
Note $string should be declared as string not var.
Oh right, that's why it's not working. Well too bad :D I thought there would be some solution for var variable, cuz i have variable that can be array or string.
Well. Zephir !== PHP :)
