Karlcarlo 0060b2798f chore: 添加缺失的静态资源文件
添加多个前端界面所需的图片、字体、音频等静态资源文件,包括:
- 管理员后台的图标、背景图、组件图片
- 移动端页面的商品图片、用户中心图片、活动图标
- 第三方库的示例图片和字体文件
- 浏览器兼容性配置文件
- 图标字体文件(eot、ttf、woff、woff2格式)

这些资源是前端界面正常显示所必需的,之前可能因版本控制忽略或遗漏而缺失。

PSR Log

This repository holds all interfaces/classes/traits related to PSR-3.

Note that this is not a logger of its own. It is merely an interface that describes a logger. See the specification for more details.

Installation

composer require psr/log

Usage

If you need a logger, you can use the interface like this:

<?php

use Psr\Log\LoggerInterface;

class Foo
{
    private $logger;

    public function __construct(LoggerInterface $logger = null)
    {
        $this->logger = $logger;
    }

    public function doSomething()
    {
        if ($this->logger) {
            $this->logger->info('Doing work');
        }
           
        try {
            $this->doSomethingElse();
        } catch (Exception $exception) {
            $this->logger->error('Oh no!', array('exception' => $exception));
        }

        // do something useful
    }
}

You can then pick one of the implementations of the interface to get a logger.

If you want to implement the interface, you can require this package and implement Psr\Log\LoggerInterface in your code. Please read the specification text for details.
