ThinkPHP 3.2 使用的一些记录

Categories 学习笔记

在 View 模板引擎中输出数组的下标值

如 数组 $list 和 下标 $data.vo.id

{$list[$data[vo][id]]}

若变量为空，赋予默认值（判断空）

{$vo.position_id|default='空'}

获得 MySQL 数据表备注

//获取备注信息
public function _get_field() {
  $model = new \Think\Model();
  $controller_name = $this->CamelCaseToUnderScore(CONTROLLER_NAME);
  $rs = $model->query("select `column_name`,`column_comment` from information_schema.COLUMNS WHERE TABLE_SCHEMA = '".C('DB_NAME')."' AND TABLE_NAME = '".C('DB_PREFIX').$controller_name."'");

  $arr = array_column($rs,'column_comment','column_name');
  return $arr;
}
//驼峰命名转下划线命名
public function CamelCaseToUnderScore($str)
{
  $dstr = preg_replace_callback('/([A-Z]+)/',function($matchs)
  {
    return '_'.strtolower($matchs[0]);
  },$str);
  return trim(preg_replace('/_{2,}/','_',$dstr),'_');
}

PHP 数组变量传递给 JS

var arr=transArr({$array|json_encode=true}); 
function transArr(obj) {
  var tem=[];
  $.each(obj, function(i) {
	tem[i]=obj[i];
  });
  return tem;
}

ThinkPHP 使用 WorkerMan 的一些记录

Categories 学习笔记

通过 composer 安装

composer require topthink/think-worker

启动

php think worker

初次使用可能会报错

[root@instance-jewlel2q www.imgram.cn]# php think worker
Starting Workerman http server...
Workerman[think] start in DEBUG mode
stream_socket_server() has been disabled for security reasons in file /home/wwwroot/www.imgram.cn/vendor/workerman/workerman/Worker.php on line 2178

原因是 stream_socket_server 函数被 php.ini 禁用

  • 运行 php –ini 找到 php.ini 文件
  • 打开 php.ini 找到 disable_functions 一项，将 stream_socket_server 禁用项删掉。
  • 重启 php-fpm。

ThinkPHP 5 引入 百度云 BaiduBCE SDK

Categories 学习笔记

项目根目录使用 Composer

composer require baidubce/bce-sdk-php

在 Controller 中引入

<?php
require '../vendor/autoload.php';//这句不用，自动引入
use BaiduBce\Services\Bos\BosClient;

测试连接

public function baidu(){
  $BOS_TEST_CONFIG =
	array(
	  'credentials' => array(
	  'accessKeyId' => '684b94f7675142d79ed2bxxxxxxxxxxx',
	  'secretAccessKey' => '0ee6b11cc38445fc8xxxxxxxxxxxxx',
	  ),
	  'endpoint' => 'https://todo.cdn.bcebos.com',
	);
  $client = new BosClient($BOS_TEST_CONFIG);
  dump($client);
}

输出结果

上传文件测试

public function baidu(){
  $BOS_TEST_CONFIG =
    array(
      'credentials' => array(
      'accessKeyId' => '684b94f7675142d79ed2bxxxxxxxxxxx',
      'secretAccessKey' => '0ee6b11cc38445fc8xxxxxxxxxxxxx',
      'sessionToken' => ''
      ),
    'endpoint' => 'https://todo.cdn.bcebos.com',
    'stsEndpoint' => '',
  );
  $client = new BosClient($BOS_TEST_CONFIG);
  $bucketName = 'path';
  $a = $client->putObjectFromFile($bucketName, 'abc.png', 'tmp/x.png');
  dump($a);
}

如果用的是百度的服务器，可能出现在线报错

[curl] 6: Could not resolve host: todo.cdn.bcebos.com; Unknown error [url]

DNS 的问题

vim /etc/resolv.conf

修改

但是修改 DNS 的方式会使无法使用内网传输，

所以需要将上传地址改为官方域名，不要用 CDN 加速域名，这样百度内网服务器之间网就可以妙传了

MySQL 中支持 emoji 表情的存储 ThinkPHP

Categories 学习笔记

MySQL 的 utf8 编码的一个字符最多 3 个字节，但是一个 emoji 表情为 4 个字节，所以 utf8 不支持存储 emoji 表情。但是 utf8 的超集 utf8mb4 一个字符最多能有 4 字节，所以能支持 emoji 表情的存储。下面介绍了关于如何修改 mysql 数据库的编码格式变为 utf8mb4 的具体方法。

找到 /etc/ 路径下的 my.cnf 文件(或 /etc/mysql/ 路径下)，通过 vim 命令 vim /etc/my.cnf 打开该文件并进行编辑，需添加如下所示配置：

[client]
default-character-set=utf8mb4

[mysqld]
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
init_connect=’SET NAMES utf8mb4'

[mysql]
default-character-set=utf8mb4
