Wordpress get_media_embedded

Question

 test text

<div class="video">
    
    <?php

        $media = get_media_embedded_in_content( apply_filters( 'the_content', get_the_content() ));
        
        print_r($media);

        
    ;?>

</div>

<div class="uitgelichttitel">
    <?php the_title();?>
</div> 

that's my code

Finally shows me the video, but I am getting this on the front-end:

Array ( [0] => )

Why?

Changing print_r($media) to print($media) removes the video.

Info about the file

This is the entire file. It's called content-video.php. WordPress automatically attached this file to the post format. When it loops through the posts it immediately checks the post format and if it is post format then it fetches the file accordingly. In this case that's content-video.php.

Extra about me

I apologize if this is a no brainer. Have been trying to learn how all of this works for a while now, including plenty of hours today, probably going to be working on figuring this out until the night. Figured maybe I could get someone to tell me what's up in easier terms, there's already a lot that I am trying to get a grasp on. Thank you. I am new to Wordpress theme development, new to PHP and new to JS.

The Goal

Pull the embed video from the post content to display on a different page.

Best Attempt

What I have thus far, which I am still trying to wrap my head around.

The Fix

Provided by TheDeadMedic:

Change "print_r" to "print current"

Answer 1

Because print_r prints a readable version of your variable $media, which will be an array as per the documentation for get_media_embedded_in_content().

You see Array ( [0] => [youtube embed] ) in your browser because it's rendering the HTML of the array element - if you check the source code of your page you would see something like:

Array (
    [0] => <iframe src="..." />
)

But to answer your problem, you should print (or echo) with current() to get the "current" element in an array, which in this case will be the HTML for the first found media element (if one exists):

print current( $media );
