Solution:

How about preg_split:

$str = 'having_tag_slugs_and_having_category1_slug_and_having_category2_slug_or_having_category3_slug';
$arr = preg_split('/(_and_|_or_)/', $str, -1, PREG_SPLIT_DELIM_CAPTURE);
print_r($arr);
Copy code

output:

Array
(
    [0] => having_tag_slugs
    [1] => _and_
    [2] => having_category1_slug
    [3] => _and_
    [4] => having_category2_slug
    [5] => _or_
    [6] => having_category3_slug
)
