Architecture optimization of PHP and database

With the rapid development of the Internet and mobile Internet, Web applications are playing an increasingly important role in our daily lives. In these web applications, PHP and databases are widely used. However, as the number of users increases, the performance problems of Web applications become more and more prominent. Therefore, PHP and database schema optimization become very important in web applications.

1. Using Caching

MySQL caching is a technology that saves data across requests. PHP can implement caching by using a caching system such as memcached or APC. This way, the PHP page will fetch data from the cache instead of fetching data from the database, which can improve performance.

2. Reduce database queries

When accessing the database, each query will bring a certain overhead. If you have multiple queries running, you should try to keep the number of queries as low as possible. You can reduce the number of database queries by combining queries using JOIN or subqueries.

3. Index optimization

Index is the way to store data in the database. It makes queries faster and reduces the load on the database server. Ensure that each field of the table has an appropriate index and avoid performance issues when querying multiple tables.

4. Database Partitioning

For large databases, partitioning is an important technology. It breaks the table into smaller partitions so that each query only needs to access the required data partitions, thus improving performance. For example, in an e-commerce website, orders can be grouped by data partitions.

5. Database Optimization

Make sure the database server has enough capacity and RAM, and runs fast enough. Optimize database server settings, such as increasing cache size or adjusting script run time. Additionally, using appropriate data types and correct data structures can improve query speed.

6. PHP Code Optimization

When designing a web application, using optimized code is key to improving performance. This includes using the latest PHP version, reducing file includes and avoiding the use of the eval() function, etc.

7. Using a CDN

A CDN (Content Delivery Network) is a technology that makes websites faster. It works by replicating website content to multiple different data centers and then using the closest data center to serve the website content. This is useful in reducing load on web servers and database servers alike, thus improving performance.

Summary:

PHP and database schema optimization in web applications is crucial to improving web application performance. Very good performance optimization can be achieved by using techniques such as caching, reducing database queries, using appropriate indexes and data structures, partitioning databases, optimizing PHP code, and using CDNs. When designing your web application, be sure to consider best practices and techniques for optimizing performance.
