As a PHP 8.2 deprecation, mb_detect_encoding and mb_convert_encoding will no longer work with these encodings. If you depended on this functionality, you can adapt your code as follows: “mb_convert_encoding($string, ‘base64’)” should become “base64_encode($string)” ...

首先是file_get_contents函数读取来自php的输入流,然后通过parse_str()函数将查询字符串解析为变量,然后存在$_PUT数组中 但是这里因为method直接默认为paramter 所以直接跳入 param 的 case,这里先让它默认判断为get 这里debug了一下分为两个过程 1、如果不传值 -> is_array(\$data) &\& array_walk_recursive(...
