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';
}
?>
