Store datetime without seconds using SQL in PHP -


i created function below in php insert ticker details in database. i'd store datetime field in database without seconds because json data updated every minute.

function insert(){          $jsonarray = json_decode(self::getticker(), true);          var_dump($jsonarray);          foreach ($jsonarray $value) {             $high = $value['high'];             $low = $value['low'];             $last = $value['last'];             $buy = $value["buy"];             $sell = $value['sell'];             $date = $value['date'];             $vol = $value['vol'];         }         $datef = gmdate("y-m-d h:i:s", $date);          $sql = "insert `ticker_history`         (`ticker_history_high`,          `ticker_history_low`,          `ticker_history_vol`,          `ticker_history_last`,          `ticker_history_buy`,          `ticker_history_sell`,         `ticker_history_date`)         values          (?, ?, ?, ?, ?, ?, ?)";         $stmt = $this->conn->prepare($sql);         $stmt->bind_param("dddddss", $high,$low,$vol,$last,$buy,$sell,$datef);         $result = $stmt->execute();         $stmt->close();          if ($result) {                 // ticker inserted             return  print_r(ticker_created_successfully);          } else{             return print_r(ticker_create_failed);         } }

the datetime column uses structure y-m-d h:i:s

it store seconds. can use php's datetime class format dates so:

$date = new datetime(); echo $date->format('y-m-d h:i'); // outputs 2017-08-18 17:05

when querying db, in clause can say:

...where datecolumn = '".$date->format('y-m-d h:i:00')."' etc

example:

$date = new datetime(); echo $date->format('y-m-d h:i:s')."\n"; // 2017-08-18 17:09:15 echo $date->format('y-m-d h:i:00')."\n"; // 2017-08-18 17:09:00

see in action: https://3v4l.org/d47pa

btw can pass in string datetime constructor

new datetime($row['datecolumn']);

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
