Array to String Conversion Error while tweaking Simplepie - php

Question

I am using SimplePie library for feed generation. I made some changes for desired output. It was working great till today.
Here is my code:
<?php
header('Content-type: text/plain; charset=utf-8');
// Include the SimplePie library
// For 1.0-1.2:
#require_once('simplepie.inc');
// For 1.3+:
require_once('autoloader.php');
// Create a new SimplePie object
$feed = new SimplePie();
// Instead of only passing in one feed url, we'll pass in an array of three
$feed->set_feed_url(array(
'http://localhost/full-text-rss/makefulltextfeed.php?url=dynamic.feedsportal.com%2Fpf%2F555218%2Fhttp%3A%2F%2Ftoi.timesofindia.indiatimes.com%2Frssfeedstopstories.cms&key=1&hash=759dbac5d2121d4b7bc31ee9119d65a44a73fb6d&max=10&links=preserve&exc=1&format=json'
));
//Caching is enabled
$feed->enable_cache(true);
//timeout
$feed->set_timeout(40);
// We'll use favicon caching here (Optional)
//$feed->set_favicon_handler('handler_image.php');
// Initialize the feed object
$feed->init();
// This will work if all of the feeds accept the same settings.
$feed->handle_content_type();
if ($feed->error)
{
echo $feed->error;
}
$newspaperName = array('Google News');
$i = 0;
$j = 0;
$response = array();
$response["NewsItems"] = array();
foreach ($feed->get_items() as $item)
{
$feed = $item->get_feed();
//$permalink =
//$NewsItems["Count"] = html_entity_decode($feed,ENT_QUOTES, "UTF-8");//html_entity_decode($item->get_id(),ENT_QUOTES, "UTF-8");
$NewsItems["ArticleLink"] = html_entity_decode($item->get_permalink(),ENT_QUOTES, "UTF-8");//$permalink;
$NewsItems["Title"] = html_entity_decode($item->get_title(), ENT_XHTML, "UTF-8");
$NewsItems["Content"]= html_entity_decode($item->get_content(), ENT_XHTML, "UTF-8");
if($i==10)
{
$i = 0;
$NewsItems["Source"] = html_entity_decode($newspaperName[$j+1],ENT_QUOTES, "UTF-8");
$j++;
}
else
{
$NewsItems["Source"] = html_entity_decode($newspaperName[$j],ENT_QUOTES, "UTF-8");;
$i++;
}
$feed = $item->get_feed();
$NewsItems["SourceLink"]= html_entity_decode($feed->get_permalink(), ENT_XHTML, "UTF-8");
$feed = $item->get_feed();
$NewsItems["SourceTitle"] = html_entity_decode($feed->get_title(), ENT_XHTML, "UTF-8");
$NewsItems["Date"]= html_entity_decode($item->get_date('j M Y | g:i a T'), ENT_XHTML, "UTF-8");
array_push($response["NewsItems"], $NewsItems);
}
echo json_encode($response);
?>
But Today suddenly I got an error:
Notice: Array to string conversion in C:\xampp\htdocs\simplepie\IndiaEnglishTopStories.php on line 38
Array{"NewsItems":[]}
Line 38 is:
echo $feed->error;
I am not a php developer so my knowledge is very much limited. I read so many answer here and I tried to implement that but still problem is there. Forgive me if you find this question stupid and annoying. Thank you for your time.

Answer 1

Your trying to echo a array this is not possible. $feed->error is an array.
Change to
foreach($feed->error as $err)
echo $err;
or
var_dump($feed->error)
or
print_r($feed->error)
How to echo or print an array in PHP?
