'id' => 1,? ? 'name' => '張三',? ? 'age' => 18? ),? array(? ? 'id' => 2,? ? 'name' => '李四',? ? 'age' => 20? ),? array(? ? 'id' => 3,? ? 'name' => '二傻子',? ? 'age' => 18? ),? array(? ? 'id' => 4,? ? 'name' => '三愣子',? ? 'age' => 19? ));if (empty($_GET['id'])) {? $json = json_encode($data);?? echo $json;}?else{?? foreach ($data as $item) {? ? if ($item['id'] != $_GET['id']) continue;? ? $json = json_encode($item);?? ? echo $json;? }}
為什么用Ajax獲取PHP數據的時候，responseText返回的是整個PHP代碼啊？下面是代碼，求大牛解答
