Why does my php function not get data from JSON array? - php

Question

I have a page that pulls information about TV shows from the TMDB as a json array with the help of the TMDB-API Wrapper. I am trying to get the page to display information on a tv shows's ['network'].
I have written a function for this that loops through the network array but I can't get it to work. Can anyone tell me what I'm doing wrong? Thanks.
This is my function that does not work.
//Get networks
public function getNetworks() {
$networks = array();
foreach($this->_data['networks'] as $data){
$networks[] = new Network($data, $this->getName());
}
return $networks;
}
Display.php
//Call the function and loop though results
echo ' <li>Networks: <ul>';
$networks = $tvShow->getNetworks();
foreach($networks as $network){
echo '<li>'. $network->getID() .'</li>';
}
This does work (written in the wrapper not me)
public function getSeasons() {
$seasons = array();
foreach($this->_data['seasons'] as $data){
$seasons[] = new Season($data, $this->getID());
}
return $seasons;
}
This does work
//Get Network
public function getNetworks() {
return $this->_data['networks'][0]['name'];
}
And then on display.php
echo '<b>'. $tvShow->getNetworks() .'</b>';
This is the json array
