php - regular expression to extract foo, bar, baz and logical operator -

string parsing

foo_and_bar_and_baz_or_doe

expected result: foo, bar, baz , doe along and, , and or.

i tried /(.*?)(_and_|_or_)/i skipping last one.

actually sting

having_tag_slugs_and_having_category1_slug_and_having_category2_slug_or_having_category3_slug

out put, looking is

having_tag_slugs having_category1_slug having_category2_slug having_category3_slug  _and_ _and_ _or_ ''

you can try following regular expression -

/(.*?)(_and_|_or_|$)/im

hope helps. let me know how goes :)
