note 112203 added to function.preg-replace

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 ---- Server IP: 91.199.167.223 Probable Submitter: 212.123.196.50 ---- Manual Page -- http://php.net/manual/en/function.preg-replace.php Edit -- https://master.php.net/note/edit/112203 Del: integrated -- https://master.php.net/note/delete/112203/integrated Del: useless -- https://master.php.net/note/delete/112203/useless Del: bad code -- https://master.php.net/note/delete/112203/bad+code Del: spam -- https://master.php.net/note/delete/112203/spam Del: non-english -- https://master.php.net/note/delete/112203/non-english Del: in docs -- https://master.php.net/note/delete/112203/in+docs Del: other reasons-- https://master.php.net/note/delete/112203 Reject -- https://master.php.net/note/reject/112203 Search -- https://master.php.net/manage/user-notes.php
