解析错误：类stdClass的对象无法转换为字符串

I'm using twitter api to retrieve fav tweets, then parse them using a template:

$favs_list = $this->connection->get('favorites/list');
$data_to_parse['fav_list'] = $fav_list;
$html = $this->parser->parse('templates/tweet_list', $data_to_parse, TRUE);
$output['html'] = $html;
$this->load->view('read', $output);

the template tweet_list is simply:

<h3>Favs:</h3>
{fav_list}
<h5>{text}</h5>
{/fav_list}

But I keep getting these two error, and repeated multiple times:

A PHP Error was encountered    
Severity: 4096     
Message: Object of class stdClass could not be converted to string     
Filename: libraries/Parser.php
Line Number: 143

A PHP Error was encountered   
Severity: Notice     
Message: Object of class stdClass to string conversion     
Filename: libraries/Parser.php    
Line Number: 143

The weird thing is that, under these errors, my html is shown in correct format. Any idea on what caused this?

I don't know optimal method but I do usually with

json_decode(json_encode ($favs_list), true);

You are trying to print out favs_list but the content is an object, and its having a hard time trying to convert that object.

Just convert the object to an array instead and use accordingly

$array = (array) $object;

in your case

$favs_list = $this->connection->get('favorites/list');
$data_to_parse['fav_list'] = (array) $fav_list;
