您可以json_decode用来将JSON转换为数组。PHP json_decode（）$jsonToArray = json_decode($json,true); // $json has the `JSON`如果您需要与key，则amount可以使用array_walk PHP array_walk（）$jsonToArray = json_decode($json,true);$res = [];array_walk($jsonToArray['return'], function($v, $k) use (&$res){ $res[$k] = $v['amount'];});输出：-Array( [1400151861513776] => 138959.22155687 [1400151861456538] => 4115.53246448 ....... ....... [2400151857916444] => 400000 [2400151857916059] => 400000)或者如果不需要key，则只能amount使用array_map PHP array_map（）$jsonToArray = json_decode($json,true);$res = [];array_map(function($v) use(&$res){ $res[] = $v['amount'];}, $jsonToArray['return']);输出 ：- Array( [0] => 138959.22155687 [1] => 4115.53246448 ....... .......)
