How to collect array indexes from different resources?

I get data from 2 different URLs, But sometimes both have the same data.

I only want to save the data in an array when the data is the same.

Getting the data from first website:

$a = 'http://firstwebsite.com';
$rss = simplexml_load_file($a);

foreach ($rss->channel->item as $item) {
$post['title'] = $item->title;
$post['link'] = $item->link;
$post['date'] = $item->pubDate;
$post['description'] = $item->description;

$articles = $post;
}


So that if I print the articles array:

echo '<pre>';
print_r($articles);
echo '</pre>';


I get:

Array
(
[0] => Array
(
[title] => SimpleXMLElement Object
(
[0] => First Item Title
)

[link] => SimpleXMLElement Object
(
[0] => http://firstitemlink.com
)

[date] => SimpleXMLElement Object
(
[0] => 18 Jun 2018 06:52:20
)

[description] => SimpleXMLElement Object
(
[0] => SimpleXMLElement Object
(
)

)

)

[1] => Array
(
[title] => SimpleXMLElement Object
(
[0] => Second Item Title
)

[link] => SimpleXMLElement Object
(
[0] => http://seconditemlink.com
)

[date] => SimpleXMLElement Object
(
[0] => 18 May 2018 12:03:03
)

[description] => SimpleXMLElement Object
(
[0] => SimpleXMLElement Object
(
)

)
)
)


Then the second website:

$b = 'http://secondwebsite.com';
$rss = simplexml_load_file($b);

foreach ($rss->channel->item as $item) {
$post['title'] = $item->title;
$post['link'] = $item->img;

$articles = $post;
}


The number of posts may vary from the 2 websites.

I want to get an array with the (title, link, description, pubDate and img), When the title is the same in both the arrays.

So that the final array would be:

Array
(
[0] => Array
(
[title] => SimpleXMLElement Object
(
[0] => First Item Title
)

[link] => SimpleXMLElement Object
(
[0] => http://firstitemlink.com
)

[date] => SimpleXMLElement Object
(
[0] => 18 Jun 2018 06:52:20
)

[description] => SimpleXMLElement Object
(
[0] => SimpleXMLElement Object
(
)

)
[img] => SimpleXMLElement Object
(
[0] => Post Img.
)
)
)


I can get all the data, But I can't all the same post data together.

I can run each in a separate function or in the same function.

I want to save this data in a database, So if there is a better way it would be great.
