Access JSON object name in PHP -


i have following json: 

{"nickname":"xadoc","level":4,"loc":"tulsa, ok, usa","score":122597,"money":29412.5,"streetnum":8,"streets":{"-91607259\/387798111":{"name":"alam\u00e9da ant\u00f3nio s\u00e9rgio","value":243,"type":1},"-91016823\/388182402":{"name":"autoestrada norte","value":18304,"type":1},"-86897820\/399032795":{"name":"autoestrada norte","value":12673,"type":1},"-973092846\/479475465":{"name":"19th ave","value":7794,"type":1},"-974473223\/480054888":{"name":"23rd ave ne","value":33977,"type":1}}}

i'm desperately trying access dynamic object names "-91607259\/387798111", how can it?

right have:

$jsonurl = "http://www.monopolycitystreets.com/player/stats?nickname=$username&page=1"; $json = file_get_contents($jsonurl,0,null,    $obj2 = json_decode($json);  foreach ( $obj2->streets $street ) {        //here want print "-91607259\/387798111" each street, please     //echo $street[0]; gives "fatal error: cannot use object of type stdclass array"     //echo $street gives "catchable fatal error: object of class stdclass not converted string"     echo '<th>'.$street->name.'</th><td>'."m ".number_format($street->value, 3, ',', ',').'</td>'; }

i imagine simplest thing decode associative arrays instead of stdclass objects

$obj2 = json_decode( $json, true );  foreach ( $obj2['streets'] $coords => $street ) {      echo $coords; }

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
