PHP开发Eaby API起步
1. https://developer.ebay.com/ 申请开发者账号

真他妈的蛋疼的ebay!!!
2. 设定应用环境.
拥有开发者账号之后,你就自动拥有了production和sandbox两个应用环境。很显然,sandbox环境是用来测试的,production是正式环境。每个环境都有DEVID,AppID,CertID,通常我们只需要AppID(具体用法后再介绍)。下面以sandbox为例:点击应用环境右侧的Configure Settings ?链接进入应用设定页,点击User Tokens链接绑定一个sandbox ebay用户,页面上很清楚,只要按照提示操作就可以了,下面是我sandbox环境绑定的User信息:图2
记住这个User Token,稍后会用到。如法炮制,将production环境也绑定一个正式ebay账号。
3. 从Quick Start Guide起步.
图3
参考图3中的链接进入Quick Start Guide.
图4
点击图4链接进入"PHP, Perl, and Python Developer Center"页,
图5
首先要点击API by feature链接页的描述,它会告诉你各种各样的API,你该使用哪个。这些API有交叉、有包含。最全面的就是Tradding API,也是最常用的。然后再去看下面具体要使用的API文档。这个真TMD蛋疼!!
现在,我们只学习Tradding API, 进入Trading API链接页
图6
看图6页下部有个“PHP Accelerator Toolkit Easy access to Trading APIs for PHP developers”
进入之后,才能下载PHP SDK,如果你点击developer.ebay.com菜单的EBAY SDK,竟然只有Java、.net版下载,唉,PHP SDK不是亲生的啊?隐藏如此深邃的地方。当然如果没有这个所谓PHP Accelerator Tookit,也没啥大不了的,自己封装一套吧,EBAY API反正是基于SOAP的。
下载PHP Accelerator Tookit地方同时可以下载几个破破烂烂的例子、一个破破烂烂的Tookit Quick Start和Programmers Guide PDF文档(至少是唯一PHP语言相关的文档),凑合着看吧。
不出意外,你能很快就运行samples中的代码,然后你开始全部API之旅。注意:只支持php5.3,如果你运行的是php5.4会有php refrence错误,根据Php notice/php fatal逐个修正吧(本博客其他文章有描述)
4. 进入全面API学习之旅.
我只能不断地唾骂:ebay的文档很乱,真的不是一家人写的!看前面图6页面上不红色圈起的链接,点击进入就看到具体API DOC了,其实,这些API文档根本不分语言,基本就是SOAP XML的直白描述,而很多链接经过东点西点基本都能进入到这样一个页面
Trading API Guide
慢慢看吧,同学们,这文档一点都不招人喜欢,甚至有点可恨!

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
