Can you provide an example or guide on how to effectively integrate the YouTube API into a PHP project to display the latest video from a channel?

To integrate the YouTube API into a PHP project to display the latest video from a channel, you will need to make use of the YouTube Data API. This involves obtaining an API key, making a request to the API to retrieve the latest video from the channel, and then parsing the response to display the video on your website.

<?php
$apiKey = 'YOUR_API_KEY';
$channelId = 'CHANNEL_ID';
$maxResults = 1;

$apiUrl = "https://www.googleapis.com/youtube/v3/search?key=$apiKey&channelId=$channelId&part=snippet,id&order=date&maxResults=$maxResults";

$response = file_get_contents($apiUrl);
$data = json_decode($response);

$videoId = $data->items[0]->id->videoId;
$videoUrl = "https://www.youtube.com/watch?v=$videoId";

echo "<iframe width='560' height='315' src='$videoUrl' frameborder='0' allowfullscreen></iframe>";
?>
