I'm writing some optimized C code that basically runs through an array and does something to each element. What it does depends on the current value of the element so something like: for (i=0; i < a_len; i++) { if (a[i] == 0) { a[i] = f1(a[i]); } else if (a[i] % 2 == 0) { a[i] = f2(a[i]); } else { a[i...

In PHP you can use square brackets on an element to access attributes: $node = /* SimpleXMLElement */ $id = $node['id']; What's weird is that $id isn't a string, It's another SimpleXMLElement. Why isn't it a string? I find myself using strval() all over the place on this. How are the square brackets working? Can I do that with my own...
