Explode string into array with no empty elements?

PHP's explode function returns an array of strings split on some provided substring. It will return empty strings when there are leading, trailing, or consecutive delimiters, like this: ``` var_dump(explode('/', '1/2//3/')); array(5) { [0]=> string(1) "1" [1]=> string(1) "2" [2]=> string(0) "" [3]=> string(1) "3" [4]=> string(0) "" } ``` Is there some different function or option or anything that would return everything except the empty strings? ``` var_dump(different_explode('/', '1/2//3/')); array(3) { [0]=> string(1) "1" [1]=> string(1) "2" [2]=> string(1) "3" } ```
