第一回做项目――跪求各路高手指导
第一次做项目――跪求各路高手指导
自学了一段时间的html、php和mysql,第一次做项目。
大概需求是这样:
1、数据导入功能(excel)
2、特殊日期的设计与修改
3、数据统计
首先实现数据的查询功能,并依据查询结果给基本的描述性统计参数。查询内容主要包括:
(1)特殊日期
(2)选定的日期段
(3)选定的周几到周几
(4)选定的时段
4、数据的绘图
首先实现数据的查询功能,并依据查询结果绘图。
(1)静态2D、3D
(2)动态的绘图
因为之前没有项目实战的经验,但是已经下定决心以后要往这方向发展,对于这个项目,本人初步还没有什么比较好的思路,请各位高手不吝赐教!非常感谢~~~
------解决方案--------------------
excel导入很简单,
日期到网上找个JS日期控件,
特殊日期不知道你指什么,
图表也到网上找个好用的,
所以最终问题主要还是数据库设计和数据查询,
不过这个项目对第一次的新手来说确实是难度高了。
------解决方案--------------------
1.设计数据库,这是首要。数据库的设计优劣直接影响后面的查询效率。
2.实现EXCEL读取内容。
3.实现读取的内容存入到数据库中(增)。
4.实现查询功能。(查)
5.特殊显示,2D/3D,估计要用到JS插件了,推荐使用armcharts,下载网址:http://www.amcharts.com/download/
所以说,还是很简单的。

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The role of HTML is to define the structure and content of a web page through tags and attributes. 1. HTML organizes content through tags such as , making it easy to read and understand. 2. Use semantic tags such as, etc. to enhance accessibility and SEO. 3. Optimizing HTML code can improve web page loading speed and user experience.
