Summary of performance optimization and code compression techniques for PHP development of public accounts

With the popularity of WeChat public accounts, more and more developers choose to use PHP language for development Development of public accounts. However, with the complexity of business logic and the increase in user visits, the performance optimization of official accounts has become particularly important. This article will summarize some performance optimization and code compression techniques for developing official accounts in PHP to improve the loading speed and response performance of the official account.

1. Performance optimization skills

1. Database query optimization:

   • Ensure that the field settings of the database table are reasonable and avoid too many redundant fields and repeated indexes;
   • Use indexes to improve query efficiency;
   • Reasonably use database caching technology, such as Redis;
   • Avoid database queries within loops and try to process them in batches;

2. Caching mechanism:

   • Use caching technology to reduce the number of accesses to the database;
   • Set the cache time reasonably, based on Business needs determine the validity period of cached data;
   • Use caching components, such as Memcached or Redis, to improve caching efficiency;
   • Cache frequently accessed data to avoid repeated calculations;

3. Front-end optimization:

   • Reduce the size of HTML, CSS and JavaScript files, compress and merge files;
   • Use CSS Sprites technology to reduce Number of image requests;
   • Reduce the number of HTTP requests and merge file requests;
   • Use asynchronous loading to improve page loading speed;
   • Optimize image size and format, use appropriate images Compression tool;
   • Avoid loading a large amount of data when the page is loaded, delay loading;

4. Code optimization:

   • Try to do your best Avoid a large number of repeated calculations in loops;
   • Avoid deep nesting and reduce the level of function calls;
   • Use efficient algorithms and data structures;
   • Optimize SQL queries , avoid full table scan;
   • Reduce the number of file references and use cache or class automatic loading;
   • Use local cache to reduce remote requests;

2. Code compression techniques

1. Compress HTML code:

   • Remove extra spaces and line breaks;
   • Delete comments and Redundant tag attributes;
   • Replace long tags with short tags;
   • Use specific tools for compression;
   • Merge HTML files to reduce HTTP requests;

2. Compress CSS code:

   • Use compression tools to compress CSS files;
   • Remove redundant spaces and comments;
   • Merge CSS files to reduce HTTP requests;
   • Use CSS compression tools, such as YUI Compressor or CSSNano;
3. ##Compress JavaScript code:
   Use compression tools to compress JavaScript files;
   • Remove redundant spaces, comments and newlines;
   • Merge JavaScript files to reduce HTTP requests;
   • Use JavaScript compression tools, such as UglifyJS or Closure Compiler;
##Image compression:

4. Use appropriate image formats, such as JPEG, PNG Or GIF;
   • Compress the image file size, such as using tools such as TinyPNG for compression;
   • Use CSS Sprites technology to reduce the number of image requests;
Summary:

Through performance optimization and code compression of official accounts, the loading speed and response performance of official accounts can be effectively improved. During the development process, we need to pay attention to database query optimization, reasonable use of caching mechanisms, and optimization of front-end and code. Using appropriate tools and techniques, we can better improve the user experience of official accounts and provide users with better services.
