在同一行中使用explode（）时如何访问数组索引？

Question

Can't wrap my head around this...

Say, we explode the whole thing like so:

$extract = explode('tra-la-la', $big_sourse);

Then we want to get a value at index 1:

$finish = $extract[1];

My question is how to get it in one go, to speak so. Something similar to this:

$finish = explode('tra-la-la', $big_sourse)[1]; // does not work

Something like the following would work like a charm:

$finish = end(explode('tra-la-la', $big_sourse));

// or

$finish = array_shift(explode('tra-la-la', $big_sourse));

But what if the value is sitting somewhere in the middle?

Function Array Dereferencing has been implemented in PHP 5.4. For older version that's a limitation in the PHP parser that was fixed in here, so no way around it for now I'm afraid.
