Explode only by last delimiter

Question

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

$string = "one_two_  ... _three_four";

$explodeResultArray = e         


        

Answer 1

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

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

Result is

one_two_three
