我有一些我想使用 PHP 解析的 json 数据。

我想提取：

ID、姓名、DESC、地址（完整）、电话和营业时间。

我努力了。

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

但出现以下错误：

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

这是我要解析的 JSON 数据。

$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";
