This is my PHP file performing an HTTP request:
$token='Food2forkKey'; //food2fork
foo2fork private key
$fooddetail=new Food($token,"json");
$pid=$_GET['first'];
//$search='https://community-food2fork.p.mashape.com/search?key='.$token.'&q='.$pid; //Food2fork
$search='http://food2fork.com/api/search?key='.$token.'&q='.$pid;
//key
echo $search;
$json=$fooddetail->call_url($search);
//echo $details;
if(!$json){
echo 'Error: Could not retrieve products list.';
exit();
}
//var_dump(json_decode($json,TRUE));
$details=json_decode($json,TRUE);
//var_dump($details);
echo $details;
$title = $details['title'];
//print_r $title;
$publisher = $details['publisher'];
//print_r $publisher;
$image=$details['source_url'];
//print_r $image;

The script fails with an "undefine index" error message. What is the reason behind that?
I use food2fork API. The returned JSON has title and publisher keys, but when I try to display the values, the script logs the above-mentioned error message.
