Note Submitter: Dustin ---- Matching substrings where the match can exist at the end of the string was non-intuitive to me. I found this because: strtotime() interprets 'mon' as 'Monday', but Postgres uses interval types that return short names by default, e.g. interval '1 month' returns as '1 mon'. I used something like this: $str = "mon month monday Mon Monday Month MONTH MON"; $strMonth = preg_replace('~(mon)([^\w]|$)~i', '$1th$2', $str); echo "$str\n$strMonth\n"; //to output: mon month monday Mon Monday Month MONTH MON month month monday Month Monday Month MONTH MONth
