PHP - Get Meta Information by EmbedURL - metadata

Question

How I will get meta information specified by EmbedURL? I have tried get_meta_tags('MY_VIDEO_URL'). But it returns nothing.
MY HTML:
<!--Video 1-->
<div class="embed-responsive-item" itemprop="video" itemscope="" itemtype="http://schema.org/VideoObject">
<video class="embed-responsive-item" controls="" loop="">
<source src="INTERNAL_VIDEO_URL">
</video>
<meta itemprop="name" content="">
<meta itemprop="duration" content="">
<meta itemprop="thumbnailUrl" content="THUMBNAIL_URL">
<meta itemprop="embedURL" content="INTERNAL_VIDEO_URL">
<meta itemprop="uploadDate" content="2021-03-27T04:10:1600Z">
</div>
<!--Video 2-->
<div class="embed-responsive embed-responsive-16by9" onclick="loadYoutubeVideoThroughYTApi(this)" data-src-id="player-1" data-yut-var="YOUTUBE_VIDEO_ID">
<meta itemprop="description" content="META_DESCRIPTION_2">
<meta itemprop="duration" content="PT1M13S">
<meta itemprop="name" content="META_TITLE_2">
<meta itemprop="thumbnailUrl" content="https://i.ytimg.com/vi/YOUTUBE_VIDEO_ID/maxresdefault.jpg">
<meta itemprop="embedURL" content="https://www.youtube.com/embed/YOUTUBE_VIDEO_ID">
<meta itemprop="uploadDate" content="2019-02-04T11:00:43.000Z">
</div>
<!--Video 3-->
<div class="embed-responsive-item" itemprop="video" itemscope="" itemtype="http://schema.org/VideoObject">
<video class="embed-responsive-item" controls="" loop="">
<source src="INTERNAL_VIDEO_URL_2">
</video>
<meta itemprop="name" content="">
<meta itemprop="duration" content="">
<meta itemprop="thumbnailUrl" content="THUMBNAIL_URL_2">
<meta itemprop="embedURL" content="INTERNAL_VIDEO_URL_2">
<meta itemprop="uploadDate" content="2021-03-27T04:10:1600Z">
</div>
As you can see the html contains three different videos with three different meta properties. So the result array should be look like this
Desired Output:
Array
(
[0] => Array
(
[url] => INTERNAL_VIDEO_URL
[meta_name] => NULL
[meta_description] => NULL // as you can see no meta tags for description
[meta_duration] => NULL
[meta_thumbnail] => THUMBNAIL_IMAGE_URL
[upload_date] => 2021-03-27T04:10:1600Z
)
[1] => Array
(
[url] => https://www.youtube.com/embed/YOUTUBE_VIDEO_ID
[meta_name] => META_TITLE_2
[meta_description] => META_DESCRIPTION_2
[meta_duration] => PT1M13S
[meta_thumbnail] => https://i.ytimg.com/vi/YOUTUBE_VIDEO_ID/maxresdefault.jpg
[upload_date] => 2021-03-27T04:10:1600Z
)
[2] => Array
(
[url] => INTERNAL_VIDEO_URL_2
[meta_name] => NULL
[meta_description] => NULL // as you can see no meta tags for description
[meta_duration] => NULL
[meta_thumbnail] => THUMBNAIL_IMAGE_URL_2
[upload_date] => 2021-03-27T04:10:1600Z
)
)
How will I get the set of array like this?

Answer 1

After so many research I have come up with a solution that gives my desired output.
<?php
function load_my_custom_attributes_from_meta_tags( $string )
{
$htmlDom = new DOMDocument();
$errorBuffer = libxml_use_internal_errors( true );
$htmlDom->loadHTML($string);
libxml_clear_errors();
libxml_use_internal_errors( $errorBuffer );
$result = Array(
"url" => NULL,
"meta_name" => NULL,
"meta_description" => NULL,
"meta_duration" => NULL,
"meta_thumbnail" => NULL,
"upload_date" => NULL
);
$arrayKeyMap = Array(
"embedURL"=>"url",
"name"=>"meta_name",
"description"=>"meta_description",
"thumbnailURL"=>"meta_thumbnail",
"duration"=>"meta_duration",
"uploadDate"=>"upload_date"
);
$main_array = array();
foreach ($htmlDom->getElementsByTagName("meta") as $tag) {
$temp = Array();
foreach ( $tag->attributes as $attribute ) {
$temp[ $attribute->nodeName ] = $attribute->nodeValue;
}
if ( array_key_exists( "itemprop" , $temp ) && array_key_exists( "content" , $temp ) && array_key_exists( $temp["itemprop"] , $arrayKeyMap ) ) {
$result[ $arrayKeyMap[ $temp["itemprop"] ] ] = $temp["content"] === "" ? NULL : $temp["content"];
}
}
return $result;
}
$file_contents = file_get_contents('PAGE_URL');
preg_match_all('/<div class=\"embed-responsive\">(.*?)<\/div>/s',$file_contents,$matches);
$all_meta_properties = $matches[0];
$meta_array = array();
foreach($all_meta_properties as $video_meta) {
$meta_array[] = load_my_custom_attributes_from_meta_tags($video_meta);
}
print_r($meta_array);
?>
