php工作笔记1-数组常用方法总结，二维数组的去重，上传图片到oss服务器

1、二维数组去重，生成二维数组

      private function array_unique_fb($array2D){

        $data = array();

        foreach($array2D  as $key =>$value)

        {

            $isFind = false;

            foreach ($data as $key1=>$value1)

            {

                if ($value1['OpenID'] == $value['OpenID']) {

                    $isFind = true;

                    break;

                }

            }

            if (!$isFind)

            {

                array_push($data, $value);

            }

        }

        return $data;

}

2、上传图片到服务器

 private function saveImage($imgurl)

    {

        $url='Application/Admin/Public/default/images/';

        if(!empty($_FILES)){

//            function uprename()

//            {

//                return time() . rand(1000, 5000);

//            }

            $rule=time() . rand(1000, 5000);

            $upload = new ThinkUpload();// 实例化上传类

            $upload->maxSize = 2097152;// 2M

            $upload->saveRule = $rule;

            $upload->exts = array('jpg', 'png', 'jpeg');// 设置附件上传类型

            $upload->rootPath  = SITE_DIR.$url;

            $upload->savePath = '';// 设置附件上传目录

            $upload->thumb = true;

            $upload->thumbPrefix = 'm_';

            $upload->thumbMaxWidth = '230';

            $upload->thumbMaxHeight = '230';

            $info = $upload -> uploadOne($imgurl);

//            var_dump($info);

//            exit;

            //将图片上传到本地

            if (!$info)

            {

                // 上传错误提示错误信息

                $err = $upload->getError();

                $result['result'] = false;

                $result['errMsg'] = $err;

                return $result;

            }

            else

            {

                $image = new ThinkImage();

                $open = SITE_DIR.$url.$info['savepath'].$info['savename'];

                $image->open($open);

                $width = $image->width(); // 返回图片的宽度

                $height = $image->height(); // 返回图片的高度

//                if($width<230 || $height<230)

//                {

//                    echo "<script>alert('上传图片的高度和宽度均应大于等于230');history.go(-

1);</script>";

//                    exit();

//                }

                //将图片裁剪为230x230并保存为corp.jpg

                $image->thumb(1423, 550,ThinkImage::IMAGE_THUMB_FIXED)->save( SITE_DIR.$url.$info

['savepath'].'m_'.$info['savename']);

                $rootPath = 'Application/Admin/Public/default/images/';

                //将头像存储到OSS

                $filed = SITE_DIR."Application/Admin/Public/default/images/".$info['savepath'].'m_'.

$info['savename'];

                $save_url = "/".$info['savepath'].$info['savename'];

                $local_url = $filed;

                $file_name= $info['savename'];

                $save_type = 'hudong';

                $module_name = 'UCenter';

                UP($save_url,$local_url,$file_name,$save_type,$module_name);

                $ossname = $info['savepath'].$info['savename'];

                $url = $rootPath.$info['savepath'].$info['savename'];

                //http://hidong-hudong.oss-cn-hangzhou.aliyuncs.com/hudong/UCenter/2015-10-

22/56289782ed389.jpg

                return $ossname;    //  2015-10-22/56289782ed389.jpg

            }

        }

    }

3、Explode(“,”,$Str)          将字符串转化为数组

   Implode(“,”,$Arr)          将数组转化为字符串

   Array_push($arr,”sss”)      将字符串插入数组

   In_Array( “aa”,$Arr)        //判断aa是否在$Arr【一维数组】中
