多对多关系Json

Question

I am using Doctrine as an ORM. I'm pretty new to this. So there is Json response I want to send of the entities. The entities are the following :

• Medicine
• Generics
• Content

Medicine and Generics have a many to many relationship and Generic and Content also have a many to many relationship. I need to show the details of the medicine as well as the generics of the medicine and the contents of the generics.

Here is my code

public function jsonSerialize()
{
    $newArray= array();
    $generics=$this->getGenerics();
    foreach ($generics as $generic){
        $array = json_decode(json_encode($generic), true);
        var_dump($array);
        array_push($newArray, $array);
    }
    var_dump($newArray);
    $xyz=array();
    $xyz1=array();
    $arratJosn = array(
            'medicineId' => $this->id,
            'medicineName' => $this->medicineName,
            'medicineQuantity' => $this->medicineQuantity,
            'medicinePrice' =>$this->medicinePrice,
            'manufactureId' =>$this->manufactureId->getmanufatureName(),
            'medicineApproved' => $this->medicineApproved,
            'medicineVersion' =>$this->medicineVersion,
            'genericDetails'=> array('genericName'=>$xyz,
                                     'genericQuantity' => $xyz1,),

    );

    foreach ($generics as $generic){
        $genericName=$generic->getGenericName();
        array_push($arratJosn['genericDetails']['genericName'], $genericName);
        $contents=$generic->getContent();
        foreach ($contents as $content){
            $genericQuantity=$content->getGenericQuantity();
            array_push($arratJosn['genericDetails']['genericQuantity'], $genericQuantity);
            $genericPrice=$content->getGenericUnit();
        }
    }

    return $this;

}

Using jsonEncode on the entity I am able to retrieve a json data , which is as follows :

{"medicineId":27,
"medicineName":"MedTest11",
"medicineQuantity":20
"medicinePrice":70,
"manufactureId":"Company2",
"medicineApproved":1,
"medicineVersion":1,
"genericDetails":{"genericName":["paracetamol","newgeneric"],
                  "genericQuantity":["30","40"]}
}

Though I want the result to be shown as

{"medicineId":27,
"medicineName":"MedTest11",
"medicineQuantity":20, 
"medicinePrice":70,
"manufactureId":"Company2", 
"medicineApproved":1, 
"medicineVersion":1,
"genericDetails":[{"genericName":"paracetamol", "genericQuantity":"30"},{"genericName":"newgeneric", "genericQuantity":"40"}] 
}

How can i achieve this?

Answer 1

To achieve this you need to push an array onto genericDetails like this

$arratJosn = array(
        'medicineId' => $this->id,
        'medicineName' => $this->medicineName,
        'medicineQuantity' => $this->medicineQuantity,
        'medicinePrice' =>$this->medicinePrice,
        'manufactureId' =>$this->manufactureId->getmanufatureName(),
        'medicineApproved' => $this->medicineApproved,
        'medicineVersion' =>$this->medicineVersion,
        'genericDetails'=> array()            
);

foreach ($generics as $generic){
    $genericName=$generic->getGenericName();
    $contents=$generic->getContent();
    foreach ($contents as $content){
        $genericQuantity=$content->getGenericQuantity();
        $genericPrice=$content->getGenericUnit();
        $genericArray = array (
            'genericName' => $genericName,
            'genericQuantity' => $genericQuantity
        );            
        array_push($arratJosn['genericDetails'],$genericArray);                
    }
}
