Get array data from JSON

Question

My target is to make an array of Objets(Article), I manage to recuperate the pmid, doi and title but when it comes to the array location , I couldn't do it, this the code I have tried:

<?php
class Article
{
    private $pmid;
    private $doi;
    private $title;
    private $location=array();

    public function setLocations($tabLocations){
        foreach ($tabLocations as $key => $value) {
            $location[]=$value;
        }
    }
    public function setPmid($_pmid){
        $this->pmid=$_pmid;
    }
    public function setDoi($_doi){
        $this->doi=$_doi;
    }
    public function setTitle($_title){
        $this->title=$_title;
    }

    //getters
    public function getTitle(){
        return $this->title;
    }
}

//get pmid from DOM
    require_once "simple_html_dom.php";
    $html=new simple_html_dom();
    $html->load_file('http://brainspell.org/search?query=psen+1');
    $pmid=array();

    foreach ($html->find('.paper-stuff') as $article) {
    $pmid[]= str_replace("/article/","",$article->find('a',0)->getAttribute('href'));
        }
//Create ALLArticles TAb
$articlesTab=array(); 

//upload data file
     $json=file_get_contents("C:\wamp\www\projet1\json\allArticles.json");
     $data=json_decode($json,true);         

    foreach ($pmid as $tabPmid) {
    foreach ($data as $key=>$value) {
        if($value["pmid"]==$tabPmid)
            {
                $details=new Article();

                $details->setPmid($value["pmid"]);
                $details->setDoi($value["doi"]);
                $details->setTitle($value["title"]);
                $details->setLocations($value['experiment']['location']);
                $articlesTab[]=$details;
            }           
     }         
 }
?>

This a portion of my JSON code:

   "papers": {
      "paper": [
         {

If there is anyone that could help me.Thanks in advance :D

Answer 1

If you notice location is another array so for you to get all its elements, it needs to be imploded. so try something like this .

$details->setLocations(implode(",",$value['experiment']['location']));

This will print the array as a string separated by comma ,; maybe you can choose what you want as the separator.

Answer 2

You simply missed $this to reference your object property in setLocations

public function setLocations($tabLocations){
    foreach ($tabLocations as $key => $value) {
        $this->location[]=$value; // $this->location is where you want to store your locations
    }
}

and by the way, I don't see any need to iterate over $tabLocations in your setter. Wouldn't

public function setLocations($tabLocations){
    $this->locations = $tabLocations;
}

do the trick too?

Or if you want to get rid of the keys:

public function setLocations($tabLocations){
    $this->locations = array_values($tabLocations);
}
