将驼峰式对象转换为下划线数组：

php// 驼峰对象转下划线数组public static function CamelToUnderLineArr($fields){ $newArr=[]; if (!is_object($fields)) { return $newArr; }

foreach ($fields as $key=> $value) { $newKey=preg_replace_callback('/([A-Z])/', function ($match) { return '_' . strtolower($match[1]); }, $key); $newArr[$newKey]=$value; }

return $newArr;}

驼峰对象转下划线数组和下划线数组转驼峰对象

1.[代码]驼峰对象转下划线数组

/*** * @param $fields 驼峰对象 * @return array */ public static function CamelToUnderLineArr($fields) { $newArr = []; if (!is_object($fields) || !get_object_vars($fields)) return $newArr; foreach ($fields as $key => $v) { $keyTmp = strtolower(preg_replace('/((?<=[a-z])(?=[A-Z]))/', '_', $key)); $newArr[$keyTmp] = $v; unset($fields->$key); } return $newArr; }

2.[代码]下划线数组转驼峰对象

/*** * @param $fields 下划线数组 * @return \stdClass */ public static function underLineArrTOCamel($fields) { $newObj = new \stdClass(); if(!is_array($fields) || !$fields) return null; foreach ($fields as $key => $v) { $keyTmp = array_reduce(explode('_',$key), function($v1, $v2) { return ucfirst($v1).ucfirst($v2); }); $keyTmp = lcfirst($keyTmp); $newObj->$keyTmp = $v; unset($fields[$key]); } return $newObj; }
