Get array data from JSON - php

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": [
{
"pmid": "6330179",
"doi": "10.1002/cne.902260203",

{

}

},
{

"experiment": [
{

"36.0,-58.0,52.0"
]
},
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);
}
