php : test for lines of array the condition range of date is between range of date -

-

i have logic problem on how filter entries within range of date.

an array $price contains prices flight depending of period of travel, ordered date:

   print_r($price)    [21] => array                     [date_beg] => 2014-07-05                     [total1] => 648     [22] => array         [date_beg] => 2014-08-05                     [total1] => 750    [23] => array         [date_beg] => 2014-08-12                     [total1] => 520

it 648 euros 2014-08-05, becomes 750 2014-08-05 ...

i have special offers @ periods.

the same information present each element of array:

 print_r($price)    [21] => array                     [date_beg] => 2014-07-05                     [total1] => 648          [special_beg] => 2014-07-07         [special_end] => 2014-08-06         [special_price] => 600     [22] => array         [date_beg] => 2014-08-05                     [total1] => 750          [special_beg] => 2013-10-27         [special_end] => 2013-12-18         [special_price] => 600     [23] => array         [date_beg] => 2014-08-12                     [total1] => 520          [special_beg] => 2013-10-27         [special_end] => 2013-12-18         [special_price] => 600

what feeding new "display" array containing details of special price each element of array promotion valid for.

something like:

          $nb_date=0;           foreach($price $a_price){                 if (($a_price['special_beg']>$a_price['date_beg']))         //+ other conditions         {                    $display[$nb_date]'special_beg']=$a_price['special_beg'];                   $display[$nb_date]'special_end']=$a_price['special_end'];                   $display[$nb_date]'special_price']=$a_price['special_price'];                   $display[$nb_date]'promo_web']=$a_price['promo_web'];                   $display[$nb_date]['promo_text']=$a_price['promo_text'];                   ...etc...                 }            $nb_date++;           }

i have tried quite few things no success.

i use datetime convert date string date object. otherwise > operator working on 2 strings , strings compared differently dates do. there may better way...

$nb_date=0;  //make sure set default timezone when working datetime class //set list: http://www.php.net/manual/en/timezones.php date_default_timezone_set('america/new_york');   //datetime object current date/time  $now = new datetime();   foreach($price $a_price){      //i *think* logic want, making sure current     //date after beginning date.      $date_beg = new datetime($a_price['date_beg']);     if ( $now > date_beg ){          $display[$nb_date]['special_beg']=$a_price['special_beg'];        ...      }     $nb_date++; }

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
