excelData[] 和 $ary_rank_data[$key]$val['key'] = $val['key']?

备注：导出的数据是数字的，强制转换成字符串。

thinkphp3.2，关于提交form表单，一般都用post，否则参数传递不过去，而且，不安全，不加action，就直接跳转到本页

$list = $this->table->field("id, add_date, count(ip) ip_count, product_id, count(product_id) product_id_count, category_id") ->where($condition) ->group('product_id') ->order('product_id_count desc') ->order('ip_count des.

foreach($obj_visit_doctor as $key=>$value){$doctor_am = array_filter($value, function($doctor){return $doctor['time'] == 1;});$doctor_pm = array_filter($value, function($doctor){return $doctor['time'] == 2;});$obj_visit_doctor[$key] = ['1' =&gt.

foreach($obj_visit_doctor as $key=>$value){$doctor_am = array_filter($value, function($doctor){return $doctor['time'] == 1;});$doctor_pm = array_filter($value, function($doctor){return $doctor['time'] == 2;});$obj_visit_doctor[$key] = ['1' =&gt.

foreach($obj_visit_doctor as $key=>$value){$doctor_am = array_filter($value, function($doctor){return $doctor['time'] == 1;});$doctor_pm = array_filter($value, function($doctor){return $doctor['time'] == 2;});$obj_visit_doctor[$key] = ['...

groupBy，放在，get，之前

date("w",strtotime("+1 days",strtotime('2021-06-08')));

$week_day = date('w');$week_day = date('w',strtotime('+6 days'));

在数组后添加：array_push($arr,$int1,$int2)在数组前添加：array_unshift($arr,$int1,$int2)错误写法：￥

子级控制器的构造函数，要继承，父级控制器的构造函数public function __construct() { $this->obj_user = new User(); parent::__construct();}

public，目录里，index.php，加上，session_start();

Type error: Argument 1 passed to App\Models\Erp::sendSms() must be an instance of Illuminate\Http\Request, none given, called in D:\demos\www\newMedia\yuanlaishini\app\Http\Controllers\RegisterController.php on line 37没有传递参数错：$res = (new Erp())-&.

数组array_merge：合并array_unique：去重array_filter：去空array_merge：键值重组$ary_model_kv = array_merge(array_filter(array_unique(array_merge($ary_model_kv1,$ary_model_kv2)))); //数组，合并，去重，去空，键值重组

return $str_status == 'replace'? '4':($str_status == 'login'? '3': ($str_status == 'register' ? '1' : '2'));

1、composer.jsonlavarel4，在require部分添加''maatwebsite/excel'':''~1.3''，laravel5，在require部分添加 ''maatwebsite/excel'':''~2.1.0''2、怎么查看laravel版本，PHP artisan --version3、composer update maatwebsite/excel4、更新成功后，在你的vendor目录下会出现maatwebsite和phpoffice这两个文件...

//婚姻状况public $ary_status = [ '1' => '启用', '2' => '禁用',];$ary_marry = $this->obj_model->ary_marry;

1、/admin/user/list?tag=12、$router->match(['post', 'get'], '/list/{tag?}', 'UserController@list')->where('tag', '[0-9]+'); //列表3、$tag = $ary_request['tag'];

{status: 0, msg: "远程保存文件失败", data: ""}思路：1、查看图片是否保存到本地2、查看远程上传的图片，是否显示3、查看图片保存到本地的路径是否正确，是否保存在相应的文件夹下，是否有路径中的文件夹，可能没有创建文件夹，本地保存错了路径config->filesystems'uploads' => ['driver' => 'local','root' => public_path('/uploads'),...

1、array_combine()循环判断一下循环一下分类的pluck数据（$obj_group_data），看看分组里面有没有这个分类的id，没有，就将该分类的id删掉2、新建一个数组，循环一下分类的pluck数据foreach ($obj_group_data as $key=>$value) { if (isset($ary_picture_data[$key])) { $ary_data[$value] = $ary_picture_data[$ke..

php，将数据（对象或数组）转化为json：json_encode($data);js，json字符串转化为json对象JSON.parse('{!! $str !!}');

//分组，每组一条$obj_data = DB::table('pic')->where('status' ,1)->where('is_deleted' ,0)->groupBy('group')->get();//分组，每组多条$obj_data = DB::table('pic')->where('status' ,1)->where('is_deleted' ,0)->get()->groupBy('group');...

解决方法：逐个检查：1、location和“:”号间不能有空格2、header('Location:'.$url); 前面不能有任何输出，包括各种echo，和在屏幕上的错误提醒，还有：include文件的各种输出3、header后的PHP代码还会被执行，所以需要在header后面exit一下4、检查.htaccess文件的重置与跳转，不要冲突了...

return "<script>alert('想要输出的内容');location.href='".$_SERVER["HTTP_REFERER"]."';</script>";return "<script language=javascript>alert('想要输出的内容');history.back();</script>";

控制器里，layout(false);

var src = "";location.href = "{{url('/download?src=')}}"+src;public function download(Request $request){ set_time_limit(0); @ini_set("memory_limit", "-1"); $url = $request->only("src")['src']; // 获取文件大小 // 直接设置浏览器header头通过浏览器下载 .

app->provinders->register方法里加上：$this->app['request']->server->set('HTTPS',true);

js，css，img路径都可以用，asset，url，./，/{{asset('/css/style.css')}}{{url('jquery/jquery.min.js')}}./images/header.png/images/header.pngurl和asset，可以配置路径，http，https，或者在和中间加public等./和/，路径不可修改...

后台，数组转json：json_encode()前台，JSON 字符串转换为对象：JSON.parse()

windows，有$_SERVER['QUERY_STRING'];$_SERVER['REDIRECT_QUERY_STRING'];$_SERVER['REDIRECT_URL'];linux，有，$_SERVER['QUERY_STRING'];$_SERVER['PATH_INFO'];没有，$_SERVER['REDIRECT_QUERY_STRING'];

$path = 123?456;$after = substr(strrchr($path, '?'), 1);$before = substr($path,0,strrpos($path,"?"));

{{substr(strrchr($item['url'], '/'), 1)}}

php只获得年月日:{{date('Y-m-d',strtotime($v['data']))}}php只获得年月:{{date('Y-m',strtotime($v['data']))}}php只获得日:{{date('d',strtotime($v['data']))}}
