my approach while insert’ing mysql i think read in stackoverflow.com “if need escaping or similar action, in time need” in verification pages verify user inputs (null or not check, length check , structural checks (eg: mail structure, custom tags structures); use $_post[''] variables inputs. during verifications, in custom error printing parts, error messages not include of $_post[''] values in message texts. interim note: utilize prepared statements , parameterized queries during php-mysql interactions. if inputs verified; before insert’ing mysql, strip tags input since don’t allow html tags other custom structured tags. (for example **bold text** === <strong>bold text</strong> ) insert user input mysql db. my approach while fetching mysql & printing output screen i apply htmlspecialchars() command print out screen mysql db my question i not sure of myself. there obvious or hidden weakness in approach? in advance php gurus’ valuable c

does returning copy of contents of array instead of direct reference improve encapsulation of class? i'm wondering if considered best practice. if understand correctly, trying encapsulate collection. if provide direct reference, there no encapsulation collection. user can want collection - set null. if providing deep copy of collection user, when modify copy, not modifying collection in class. the best practice encapsulate whole collection never giving user reference collection. instead, interface via class methods. if need iterate on whole collection, best return iterator on collection, provide read-only access it. say example have class bookcollection, has private list data member. if want consumers of code able add , remove books, etc., provide methods them so. here example code: public class bookcollection { private list<book> books; public bookcollection() { this.books = new arraylist(); } public void addbook(book book) {

i'd know why code below prints each letter of test on dartpad , , throws exception on terminal . mean, strings in dart not iterable, don't understand how works on dartpad; i'd expect exception there well. ideias? void main() { var test = 'test'; (var t in test) { print(t); } } i tested dart 1.14.0, happening in previous versions well. i guess because dart converted javascript , javascript supports iterating on strings , performance reasons there no additional checks prevent it. what imho bug, analyzer doesn't show warning, when test explicitely typed string void main() { string test = 'test'; (var t in test) { print(t); } } when enable strong-mode, warning though. my_project/.analysis_options analyzer: strong-mode: true type check failed: test (string) not of type iterable for both var test = 'test'; // or string test = 'test';

i've upgraded devart 7.5 , few functions not working properly. specifically, i've got function returns ienumerable: protected ienumerable<budgettotals> gettotals(decimal groupid, decimal budgetid) { using (ssinpatdatacontext dc = new ssinpatdatacontext()) { object[] ids = new object[2] { groupid, budgetid }; string sqlstr = "..." var query = dc.executequery<budgettotals>(sqlstr, ids); return query; } } to point works fine, , return variable " query " holds correct values. the problem when calling gettotals object not set: ... var query = gettotals(grpid,bdgid); foreach(budgettotals bt in query) { ... } now, when control reaches "in" in foreach instruction exception thrown message "object not set instance of object" , puzzling me because a) working fine and b) object is set within gettotals funcion. i work things around changing return value ienumerable

my application consists of several fragments. until i've had references them stored in custom application object, beginning think i'm doing wrong. my problems started when realized fragment's references mactivity becomes null after orientation change. when call getactivity() after orientation change, nullpointerexception thrown. have checked fragment's onattach() called before make call getactivity(), still returns null. the following stripped version of mainactivity, activity in application. public class mainactivity extends baseactivity implements onitemclicklistener, onbackstackchangedlistener, onslidingmenuactionlistener { private listview mslidingmenulistview; private slidingmenu mslidingmenu; private boolean mmenufragmentvisible; private boolean mcontentfragmentvisible; private boolean mquickaccessfragmentvisible; private fragmentmanager mmanager; @override public void oncreate(bundle savedinstancestate) {

recently started looking @ functional languages make algorithmic parts of application more reliable. of course bumped haskell. prepared many surprises me laziness. simple things become , slow. so i'm wondering there language can use write small algorithms in functional style without unnecessary laziness causes more problems helps. the program should compiled win32/64 native code (preferably dll) , have comparable performance c++. ocaml closest haskell, it's strict , impure. it's successor ml . ocaml, ml, , haskell can compiled machine code on common platform. in experience, though, laziness great feature once sense how works.

this code, rewritecond %{document_root}application/public%{request_uri} -f [or] rewritecond %{document_root}application/public%{request_uri} -d rewriterule application/public/.* - [l] but when entered localhost/css/style.css 404 page, although application/public/css/style.css exists. i think mean: rewriteengine on rewritebase / rewriterule ^application/public/.* - [l] rewritecond %{document_root}/application/public%{request_uri} -f [or] rewritecond %{document_root}/application/public%{request_uri} -d rewriterule .* /application/public/$0 [l] the first rewriterule prevent following rule being executed when url starts /application/public/ . prevent following rule being applied more once, although unlikely happen in specific case. the second rule(-set) internally redirect request /application/public/ folder, if , if requested filename/directory exists in folder.

i come windows environment, i'm bit lost making transition writing things in linux. say i've got simple c/c++ application so: int main(int argc, char** argv) { int h = open("something"); while (true) { // work usleep(10000); } close(h); } in windows, i'd use getasynckeystate() (or other sort of keyboard checking functionality) escape key, , break out of loop when pressed. way close(h) called, , i'd cleanup need to. the way i've been terminating applications in linux has been using ctrl + c , reading means sends sigint , , 'friendly' way cause application quit. however, in experience, that's caused sorta drop , close wherever when got signal (meaning post-loop cleanup never runs.) some have suggested use signal() listen sigint , others disagree method. (plus, tends create bit more differences between how things done between windows , linux, , i'd stay close possible running on both platf

i have built simple timezone helper cakephp app using various examples here on stack overflow saves users zone against user record. e.g. europe/london. to see helper: http://pastebin.com/vgivwqhj when user logs application, save date/time of when logged in can display list of logs user security reasons. e.g. $this->user->savefield('lastlogin', date('y-m-d h:i:s')); however date pull server date/time. how can make use of timezone of user amend it? i tried: $date = new datetime(null, new datetimezone($user['user']['timezone'])); and then: $this->user->savefield('lastlogin', $date->date); null... but if debug $date example: object(datetime) { date => '2013-04-01 15:22:32' timezone_type => (int) 3 timezone => 'europe/london' } 1.) doing wrong? how pull datetime object? 2.) way handle this? means have replace date() calls snippet users time. 3.) won't dates on website

i'm trying use python create small program, show current prices of theoretical portfolio, , offer option refresh portfolio, or new quote of choice. i can work in program, problem i'm having defined functions. if @ run_price1(), you'll notice identical of run_price(); run_price() located within update function. if take out of update function, update function doesn't work. if don't list somewhere outside of update function, later user input doesn't work. the question: looking either way call function defined within function, or way use defined function inside of secondary function. my code: import mechanize bs4 import beautifulsoup def run_price1(): mybrowser = mechanize.browser() htmlpage=mybrowser.open(web_address) htmltext=htmlpage.get_data() mysoup = beautifulsoup(htmltext) mytags = mysoup.find_all("span", id=tag_id) myprice = mytags[0].string print"the current price of, {} is: {}".form
