使用PHP脚本解析JSON数据字符串

Question

I have some json data that I would like to parse using PHP.

I would like to extract:

ID,NAME,DESC,ADDRESS (full),PHONE and HOURS.

I have tried.

$json = json_encode( $value, true );
foreach($json['results'] as $result) {
echo 'Title: ' . $result['general']['name'] . '<br />';
}

but getting following error:

PHP Warning:  Illegal string offset 'results' in ...
PHP Warning:  Invalid argument supplied for foreach() in ....

Here is the JSON data that I want to parse.

$json = json_decode( $value, true );
if (isset($json['results']) && is_array($json['results']) ) {
        foreach($json['results'] as $result) {
              echo 'Title: ' . $result['general']['name'] . '<br />';
        }
}
else echo "\$json['results'] is not an array";
