implode array in php

I have following array ... I am trying to implode it but having difficulties

require 'parserss.class.php'; 
// Second step, create new object 
$ob = new ParseRSS;
$example_ = $ob->parse('http://www.espncricinfo.com/rss/content/feeds/news/6.xml'); 

print_r($example_); 

//echo "'" . implode("','",$example_[items] => Array) . "'";


echo implode(', ', array_map(function ($entry) {
  return $entry['title'];
}, $example_));
