php - storing string that has unicode character in it -

-

i have string has following content:

  \ud83c\udf80new stuff \u0026 second stuff\n\ud83d\udcf1sms\/ kik : 085738566676 \/ veinshop\n\u26d4 item exclude ongkir\n\u2708shipping mon-fri\n\ud83d\udcb0bca only\n\ud83d\ude90jne\n\ud83c\udfe1 denpasar-bali

i wanted store in mysql database gives me empty. using doctrine2 orm interface database. here's entity string property:

class shop {   /**      *      * @var string      * @orm\column(name="bio", type="string", nullable=true)      */     private $bio;   /**      * set bio      *      * @param string $bio      * @return instagramshop      */     public function setbio($bio)     {         $this->bio = $bio;          return $this;     }      /**      * bio      *      * @return string       */     public function getbio()     {         return $this->bio;     } }

when set shop entity bio , call persist on entity. stored value null. i've set table collation utf8mb4 , charset in dbo utf8mb4

you have config looks this:

doctrine:     dbal:         default_connection: default         connections:             default:                 dbname: %database_name%                 ...                 charset: utf8mb4

make sure charset set utf8mb4. connection collation.

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()? ...

c++ - Clear the memory after returning a vector in a function -

-
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.
