$stmt = $db->prepare('select email users email = :email'); $stmt->execute(array(':email' => $_post['email'])); $row = $stmt->fetch(pdo::fetch_assoc);    $stmt->execute(array(':email' => $_post['email'])); $row = $stmt->fetch(pdo::fetch_assoc);  if(!empty($row['email'])){     $error[] = 'email provided in use.';      ?> 

    //hash password  $hash = password_hash($password, password_bcrypt, array("cost" => 10));     //create activation code     $activasion = md5(uniqid(rand(),true)); ?>     <?     if($this->input->post())          $data = array(             'username' => $this->input->post('username'),             'email' => $this->input->post('email'),             'password' => $hash,             'role' => $this->input->post('roles')                );          $this->your_model->add_user($data); ?> <?          function add_user($data)     return $this->db->insert('login', $data);

`

line 169= if($this->input->post())

"$this" available within object context.

 <?php //class  class foo  {     //property     private $bar = 'gold';              //method     public function getbar()     {         return $this->bar;     } } ?>

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 ...
