Answer

Solution:

Try this:

You are getting the whole post object in the $speakerpostid array. You need to store only the post id.

$atts['speakersname'] = 'abc,xyz,prq'; // post title
$getspeakertitle = explode(',', $atts['speakersname']);
$speakerpostid = array();
foreach ($getspeakertitle as $value) {
    $page_obj = get_page_by_title($value, OBJECT, 'speaker');
    $speakerpostid[] = $page_obj->ID;
}
echo "<pre>";
print_r($speakerpostid);
