PHP - Get variable values in string

Question

I’m new in Wordpress and PHP and I’m having a little problem rsrs

I have a very large string that I get dynamically. This string is actually an array of various values and variables. I would like to take all the values contained in the videoID variable that repeats N times within that array (which is actually a string).

Or, in other words, I’m trying to use the Youtube API to show the content of a playlist on my site. I could only get a GIANT string using file_get_contents at the url https://www.googleapis.com/youtube/v3/playlistItems?part=contentDetails&maxResults=50&playlistId=ID_DA_PLAYLIST&key=API_KEY . If anyone can help me do that :)

Thank you!

I created an API_KEY to answer your question. :)

The json object that the Youtube API sends is big and has a lot of details, if you want to mount an array only with the video ids, you can do the following:

<?php

$playlist = "SUA_ID_DA_PLAYLIST";
$api_key = "SUA_API_KEY";

// URL com ID da API e da lista de reprodução
$url_do_youtube = "https://www.googleapis.com/youtube/v3/playlistItems?part=contentDetails&maxResults=50&playlistId=".$playlist."&key=".$api_key;

$json = file_get_contents($url_do_youtube);

$obj_videos = json_decode($json);

//var_dump($obj_videos);

$lista_videos = $obj_videos->items;

$lista_id_videos = array();

foreach($lista_videos as $obj_video)
{
    $lista_id_videos[] = $obj_video->contentDetails->videoId;
}


var_dump($lista_id_videos);
