json_decode在php中返回null [关闭]

Question

I am trying to parse json using json_decode in php. It is failing for a url, Can any one tell me why its failing and is there ant alternative to json_decode in php ?

Here is my code

$url='https://espn.go.com/travel/sports/calendar/getList.json?&xhr=1&date=20121027&type=list&query=null&myTeams=';
$html = file_get_html($url);     
$json=json_decode($html,true);

//json is null here

Answer 1

file_get_html is PHP Simple HTML DOM Parser Not default PHP function It should be

 $html = file_get_contents($url);     

Please also Note that the returned JSON has an error of Malformed UTF-8 characters, possibly incorrectly encoded

To Fix THis

$url = 'http://espn.go.com/travel/sports/calendar/getList.json?&xhr=1&date=20121027&type=list&query=null&myTeams=';
$html = file_get_contents($url);
$json = preg_replace('/,\s*([\]}])/m', '$1', utf8_encode($html));
$json = json_decode($json);
echo "<pre>";
print_r($json);

Output

    [nfb] => Array
        (
            [0] => stdClass Object
                (
