i have line of code looks this: myobject.phonenumber = '+' + thephoneprefix + thebiznumber; basically, i'm creating phone number in e164 format , assign string string property of object. thephoneprefix short holds international phone prefix , thebiznumber string holds phone number digits. why didn't compiler bug when concatenating short in string in first place? , why '+' + 1 equal 44?? pretty hard bug track because there no compile error , 44 phone prefix uk "looked" working because client-side code saw uk number. why 44? thanks. why didn't compiler bug when concatenating short in string in first place? string concatenation using + sign internally calls string.concat , internally calls tostring on each parameter. hence no error. why '+' + 1 you doing character/numeric arithmetic. 43 being value of + , short/int 1 44. because of operator + associativity left right first character/numeric additio...

note : question has been asked in context of c++ regexp_replace (see here ). however, occurred me might of interest in oracle universe, too. wording of question has been adopted kind permission of original author. perl has e regex modifier allows perl code rather string formulate replacement: http://perldoc.perl.org/perlretut.html#search-and-replace though example not greatest there switches accomplish this. of understand perl here's example makes more sense: $string = "stackoverflow user: old faithful"; $string =~ s/:\s*(.*)$/$1 == "old faithful" ? ": ".$1." awesome!" : ": ".$1." ???"/e; print $string; #will print "stackoverflow user: old faithful awesome!" is there regex_replace variant in (pl)sql allow me similar? in code inline replacement. unfortunately, regex_replace doesn't cater dynamically generated replacement strings. however, can come close. answer contains 3 variations...

i've got url string, example: http://example.com/sub/sub2/hello/ i'd add subfolder php, before hello , should this: http://example.com/sub/sub2/sub3/hello/ i thought using explode separate url slashes, , adding 1 before last one, i'm pretty sure on complicate it. there easier way? this should work you: (here put folder between basename() , dirname() of string right before last part of url) <?php $str = "http://example.com/sub/sub2/hello/"; $folder = "sub3"; echo dirname($str) .
