PHP - For loop only returns last variable in array

I am having some issues getting my extremely messy code to submit data properly. Currently I am scraping a website which harbors many images and trying to collect them all and store them accordingly via my WordPress the_content selection.
Here's what I've got going so far, this is returning the images almost without any issues when I load it via a standard loop.
foreach ($html2->find('.entry-content img') as $image) {
$imageurl = $image->src;
$new = '<img src="' . $imageurl . '" style="height: auto; width: 100%;margin-bottom: 3px;">';
print $thecontent = htmlspecialchars($new); print '<br>';
} foreach ($html2->find('iframe') as $video) {
$videourl = $video->src;;
$new = '<iframe src="' . $videourl . '" scrolling="no" frameborder="0" width="100%" allowfullscreen="true" webkitallowfullscreen="true" mozallowfullscreen="true"></iframe>';
print $thecontent = htmlspecialchars($new); print '<br>';
}
The above code will return something that looks like this containing 1 - how ever many images + videos we're trying to gather.
<img src="https://www.example.com/some-image-path-here.jpg" style="height: auto; width: 100%;margin-bottom: 3px;">
<img src="https://www.example.com/some-image-path-here.jpg" style="height: auto; width: 100%;margin-bottom: 3px;">
<img src="https://www.example.com/some-image-path-here.jpg" style="height: auto; width: 100%;margin-bottom: 3px;">
<img src="https://www.example.com/some-image-path-here.jpg" style="height: auto; width: 100%;margin-bottom: 3px;">
Now here's what I am using to try and upload the content to my WordPress site (everything except $content appears to be working properly.
$content = $thecontent;
$my_post = array(
'post_title' => wp_strip_all_tags( trim( $title ) ),
'post_content' => $content,
'post_status' => 'publish',
'post_author' => 2,
'post_category' => array(2),
'post_date' => date('Y-m-d H:i:s')
);
$post_id = wp_insert_post( $my_post );
remove_filter('content_save_pre', 'wp_filter_post_kses');
remove_filter('content_filtered_save_pre', 'wp_filter_post_kses');
The above code returns the following within my WordPress the_content portion, which is the first image only, how can I make this work?
<img src="https://www.example.com/some-image-path-here.jpg" style="height: auto; width: 100%;margin-bottom: 3px;">
Note: The portion which is storing the WordPress data is being loaded inside of our initial parse loop, but outside of the loop which is collecting the images + videos.

Each time round the loop your just collecting one piece of information and setting $thecontent to that field and printing it out. You need to add these to together to get a string containing all of the content...
$thecontent = '';
foreach ($html2->find('.entry-content img') as $image) {
$imageurl = $image->src;
$new = '<img src="' . $imageurl . '" style="height: auto; width: 100%;margin-bottom: 3px;">';
$thecontent .= htmlspecialchars($new).'<br>';
}
foreach ($html2->find('iframe') as $video) {
$videourl = $video->src;;
$new = '<iframe src="' . $videourl . '" scrolling="no" frameborder="0" width="100%" allowfullscreen="true" webkitallowfullscreen="true" mozallowfullscreen="true"></iframe>';
$thecontent .= htmlspecialchars($new).'<br>';
}
print $thecontent;
Note where in each loop I use .= to append the new content to the end of the list. The final content is printed out and should be used
