API得到标题php

I'm using Tumblr API trying to get a Title of a blog. The code I have found does not work for me.

$result = json_decode(file_get_contents('http://example.tumblr.com/api/read/json?num=0'));
$print_r($result); 
echo $result[1]; 

I'm trying to echo out Ex-Sample but it's giving me blank results. What am I doing wrong?

Thank you

Try this. (tested)

$result = str_replace(array('var tumblr_api_read = ', '};'), array('', '}'), file_get_contents('http://example.tumblr.com/api/read/json?num=0'));
$data   = json_decode($result);
echo $data->tumblelog->title;

$print_r($result); 
^---you do not have a `$print_r` variable, so you're trying to execute a non-existent function.

json_decode also RETURNS the decoded data. You code should be

$json = file_get_contents(...);
$data = json_decode($json);
echo $data['whatever'];
