PHP Question

Get youtube title with php script

I would like to get the title of a youtube video in a variable, but everything I tried, didn't work. A part of the code below returns the title snippet in variable $output:


{ "items": [ { "snippet": {
"title": "Hardwell Live at Ultra Music Festival Miami 2016" } } ] }


But how could I get only the title in a variable?

<?php


function curl_download($Url){

// is cURL installed yet?
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}

// OK cool - then let's create a new cURL resource handle
$ch = curl_init();

// Now set some options (most are optional)

// Set URL to download
curl_setopt($ch, CURLOPT_URL, $Url);


// Include header in result? (0 = yes, 1 = no)
curl_setopt($ch, CURLOPT_HEADER, 0);

// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 10);

// Download the given URL, and return output
$output = curl_exec($ch);

// Close the cURL resource, and free system resources
curl_close($ch);

return $output;
}

$response = curl_download('https://www.googleapis.com/youtube/v3/videos?id=m1ssAFzaCsU&key=AIzaSyBj5GoJlQ4XzebaG6H2tp_WVuQ03JEOOss&fields=items(snippet(title))&part=snippet');

if ($response) {

$xml = new SimpleXMLElement($response);
$title = (string) $xml->title;
echo $title;

} else {

// Error handling.

echo 'error';
}

?>

Answer

$output is a JSON string, use json_decode to parse it :

$output = '{ "items": [ { "snippet": { "title": "Hardwell Live at Ultra Music Festival Miami 2016" } } ] }';
$output_decoded = json_decode($output);
$title = $output_decoded->items[0]->snippet->title;
// $title is now 'Hardwell Live at Ultra Music Festival Miami 2016';

Adapted for your code :

<?php


function curl_download($Url){

    // is cURL installed yet?
    if (!function_exists('curl_init')){
        die('Sorry cURL is not installed!');
    }

    // OK cool - then let's create a new cURL resource handle
    $ch = curl_init();

    // Now set some options (most are optional)

    // Set URL to download
    curl_setopt($ch, CURLOPT_URL, $Url);


    // Include header in result? (0 = yes, 1 = no)
    curl_setopt($ch, CURLOPT_HEADER, 0);

    // Should cURL return or print out the data? (true = return, false = print)
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    // Timeout in seconds
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);

    // Download the given URL, and return output
    $output = curl_exec($ch);

    // Close the cURL resource, and free system resources
    curl_close($ch);

    return $output;
}

$response = curl_download('https://www.googleapis.com/youtube/v3/videos?id=m1ssAFzaCsU&key=AIzaSyBj5GoJlQ4XzebaG6H2tp_WVuQ03JEOOss&fields=items(snippet(title))&part=snippet');

if ($response) {

    $response_decoded = json_decode($response);
    $title = $response_decoded->items[0]->snippet->title;
    echo $title;

} else {

    // Error handling.

                echo 'error';
}

?>
