Json Array PHP Youtube Api v2无法从$ t接收字符串

Question

I get channel json information from the youtube api v2 with following code:

$json = json_decode(file_get_contents("http://gdata.youtube.com/feeds/api/users/lefloid?alt=json"),true);

And then try to get the author name

echo $json["entry"]["author"][0]["name"]["$t"];

But this code doesnt work so I try find the problem.

$json = json_decode(file_get_contents("http://gdata.youtube.com/feeds/api/users/lefloid?alt=json"),true)["entry"]["author"][0]["name"];
echo "<pre>";
print_r($json);
echo "</pre>";

output:

Array([$t] => LeFloid)

but the echo after this code doesnt work

echo $json["$t"];

How can I get finally the author name?

Answer 1

The following code will produce the author's name.

<?php
    $json = json_decode(file_get_contents("http://gdata.youtube.com/feeds/api/users/lefloid?alt=json"),true);
    print_r($json['entry']['author'][0]['name']['$t']);
?>

When you tried

echo $json["$t"];

it wouldn't work because you were tyring to access $t at the top level of the array when it needs to be preceded by $json["entry"]['author'][0]['name']
