仅由最后一个定界符爆炸 [英] Explode only by last delimiter

问题描述

有没有一种方法可以使用爆炸功能仅在最后一个定界符出现时爆炸?

is there a way to use explode function to explode only by last delimiter occurrence?

$string = "one_two_  ... _three_four";

$explodeResultArray = explode("_", $string);

结果应为:

$expoldeResultArray[0] is "one_two_three ...";

$expoldeResultArray[1] is "four";

推荐答案

不需要解决方法. explode()接受一个负数限制.

There is no need for a workaround. explode() accepts a negative limit.

$string = "one_two_three_four";
$part   = implode('_', explode('_', $string, -1));
echo $part;

结果是

one_two_three
