mysql - PHP Best way to get to compare to assoc arrays and create a new one with matchings -


image have 2 assocs arrays:

1

array    0 =>      object(stdclass)       public 'id' => string '1'        public 'desc' => string 'lorem ipsum'    1 =>      object(stdclass)       public 'id' => string '5'        public 'desc' => string 'lorem ipsum'    2 =>      object(stdclass)       public 'id' => string '7'        public 'desc' => string 'lorem ipsum'    3 =>      object(stdclass)       public 'id' => string '8'        public 'desc' => string 'lorem ipsum'    4 =>      object(stdclass)       public 'id' => string '12'        public 'desc' => string 'lorem ipsum'    5 =>      object(stdclass)       public 'id' => string '13'        public 'desc' => string 'lorem ipsum'

2

array    0 =>      object(stdclass)       public 'id' => string '2'        public 'desc' => string 'lorem ipsum'    1 =>      object(stdclass)       public 'id' => string '5'        public 'desc' => string 'lorem ipsum'    2 =>      object(stdclass)       public 'id' => string '7'        public 'desc' => string 'lorem ipsum'    3 =>      object(stdclass)       public 'id' => string '58'        public 'desc' => string 'lorem ipsum'    4 =>      object(stdclass)       public 'id' => string '66'        public 'desc' => string 'lorem ipsum'    5 =>      object(stdclass)       public 'id' => string '78'        public 'desc' => string 'lorem ipsum'

what best way create new array, have entries matches @ 'id'? doing sql query inner join on 2 tables contain data.

the result should this:

array    0 =>     object(stdclass)       public 'id' => string '5'        public 'desc' => string 'lorem ipsum'    1 =>      object(stdclass)       public 'id' => string '7'        public 'desc' => string 'lorem ipsum'

i trying around bit, doing array map checking each object if there equivalent in other array seems not best solution this.

thanks

this works me:

<?php  $arr1 = array(     (object) array(         'id' => '4',         'desc' => 'four'     ),     (object) array(         'id' => '5',         'desc' => 'five'     ),     (object) array(         'id' => '3',         'desc' => 'three'     ) );  $arr2 = array(     (object) array(         'id' => '2',         'desc' => 'two'     ),     (object) array(         'id' => '4',         'desc' => 'four'     ),     (object) array(         'id' => '6',         'desc' => 'six'     ) );  $arr3 = array(); foreach( $arr1 $obj1 ){     foreach( $arr2 $obj2 ){         if( $obj1->id == $obj2->id ){             $arr3[] = $obj1;             break;         }     } }  echo '<pre>'; print_r( $arr3 ); echo '</pre>';

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...

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
