PHP explode 在一行中获取特定的索引值

Question

我想做

<?php 
$str = "I want to access 2nd or 3rd index in one line";
echo explode(" ",$str)[2];
?>

我们可以使用

轻松访问第一个索引

stristr($str," ",true);  //For php version >= 5.3

或

$foo = array_shift(explode(':', $foo));

或

list($str) = explode(" ", $str);

但是

如何在一行中访问特定索引 [1]、[2] 或 [3]？？？

5.4+

<?php echo explode(" ","I want to access 2nd or 3rd index in one line")[2]; ?>
