Perform sorting of array that contain alphanumeric elements php -


hi have array like

$test = ['orange 2016','orange 2017' ,'mango 2018' ,'apple 2018' ,'apple 2015'];

i have sort array array should descending order respect year.i tried different type of sorting.but fails.my expected result below

$test = ['apple 2018','mango 2018','orange 2017','orange 2016' ,'apple 2015'];

my code shared below

  $test = ['jan 2016','jan 2017' ,'dec 2018' ,'april 2018' ,'march 2015'];  echo "<pre>"; print_r($test); echo "</pre>";  $n = count($test); for($i=0;$i<$n;$i++){     for($j=$i+1;$j<($n);$j++){          preg_match('#(\d+)$#',$test[$i],$year_one);          preg_match('#(\d+)$#',$test[$j],$year_two);          if($year_one[1] < $year_two[1]){             $temp = $test[$j];             $test[$j] = $test[$i];             $test[$i] = $temp;          }          if($year_one[1] == $year_two[1]){             if(strcmp($test[$j],$test[$i]) < 0 ){                 $temp = $test[$j];                 $test[$j] = $test[$i];                 $test[$i] = $temp;             }          }     } }  echo "<pre>"; print_r($test); echo "</pre>";

it little complicated code.is other simplest method achieving desired result?

so explode words in 2 new arrays , sort them multisort , year leading array.
rebuild new result array.

$test = ['red orange 2016','orange 2017' ,'mango 2018' ,'granny smith apple 2018' ,'apple 2015'];  $a = array(); // create 2 new arrays hold fruit , year $b = array(); $temp = array(); foreach($test $item){     $temp = explode(" ", $item); // explode fruit/year temp array     $a[] = implode(" ", array_splice($temp, 0, -1)); // implode last item "fruit"     $b[] = end($temp); // last item year }  array_multisort($b, $a); // sort new arrays  $result=array(); for($i=count($b)-1; $i>=0; $i--){ // looping backwards count() once. (faster)     $result[] = $a[$i] . " " . $b[$i]; // rebuild new array correct sorting. } var_dump($result);

edit; use temp array hold exploded values , use array_splice , implode build fruits, , separate year.

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
