PHP分解在一行中获取特定索引值

我想做什么

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

或

或

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]; ?>

秒

strtok($string, " "); echo strtok(" ");

还是第三

strtok($string, " "); strtok(" "); echo strtok(" ");

---

这样做可以获得特定的索引值

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

您只能执行回波爆炸（“，$str）[2]在PHP中>=5.4，我记得。是的，你是对的，我刚刚在5.4中测试了它，任何其他与其他版本一起使用的好解决方案都会很感激：）他想让它在5.3中工作：）查看OP帖子下面的评论。这些评论是在答案之后发布的

strtok($string, " "); echo strtok(" ");

strtok($string, " "); strtok(" "); echo strtok(" ");

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