用php清理JSON

首先将JSON解析为PHP数组，然后像处理常规请求内容一样对数组中的每个值进行过滤，您可以将JSON键映射到原理图过滤器和标志/选项，例如

$filters = array(    'email'=>FILTER_VALIDATE_EMAIL,     'url'=>FILTER_VALIDATE_URL,     'name'=>FILTER_SANITIZE_STRING,    'address'=>FILTER_SANITIZE_STRING);$options = array(    'email'=>array(        'flags'=>FILTER_NULL_ON_FAILURE    ),     'url'=>array(        'flags'=>FILTER_NULL_ON_FAILURE    ),     //... and so on);$inputs = json_depre($your_json_data);$filtered = array();foreach($inputs as $key=>$value) {     $filtered[$key] = filter_var($value, $filters[$key], $options[$key]);}
