Question

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" }

Try preg_split.

$exploded = preg_split('@/@', '1/2//3/', -1, PREG_SPLIT_NO_EMPTY);
