    }
}

I want to capture, with PHP, the name of the author, which in the case is in the node author 0 name $t.

The code I have so far:

<?php

// código do vídeo 
$video_ID = 'your-video-ID';

// substitua pelo código do vídeo 
// trazendo o json com as informações do vídeo
$JSON = file_get_contents("gdata.youtube.com/feeds/api/videos{$video_ID}?v=2&alt=json");

// decodificando e transformado o json em um objeto / array 
$JSON_Data = json_decode($JSON);

// guardando em uma variável a quantidade de views 
$views = $JSON_Data->{'entry'}->{'yt$statistics'}->{'viewCount'};

// exibindo na tela 
echo $views;

?>
php json

  • Friend, what have you tried in PHP? Already have some code?

  • If you give a Json.Parse("your file") you can turn your json into a list of objects?

Use the function json_decode and pass true in the second argument to turn the return into an associative array. Then call the key you want.

$arr = json_decode($json, true);
echo $arr['entry']['author'][0]['name']['$t'];

If you have the string already stored in a variable just use the function json_decode of PHP.

This function will convert the string to JSON for a array.

Then staying that way

$parseObj = json_decode($json); //Tipo objeto
$parseArray = json_decode($json, true); //Tipo Array

echo $parseObj->entry->author[0]->name->{'$t'}; //Pijdusa Goruk
echo $parseArray['entry']['author'][0]['name']['$t']; //Pijdusa Goruk

PHP has functions to work with JSON. What you’re looking for is json_decode.

To get the desired key, just navigate between the array indexes

<?php

$content = file_get_contents('myJson.json');

// Segundo argumento 'true' retorna um array associativo
// ao invés de um objeto em stdClass
$array = json_decode($content, true);
echo $array['entry']['author'][0]['name']['$t'];

// Se preferir, pode usar a notação em objeto
$obj = json_decode($content);
echo $obj->entry->author[0]->name->{'$t'};
