jQuery – accessing a child element
Let’s assume you have a <div> element with 20 <a> tags inside, and each <a> tag has a <span> somewhere inside it. If you’d like to access all those spans you should use this jQuery line:
$('div a').children(':first-child') |
Common mistake is to query like that:
$('div a:first-child') |
but that is completely other thing, and will return the first <a> tag, not the <span> inside all of them.

What about anonymous objects
I’d like to see anonymous objects, yet again like in JS, in PHP. This is really powerfull, I hope more programmers would like to see such features in PHP.
