PHP kernel exploration variables (6)

A year ago, due to the saturation of work, I was busy changing jobs, and I basically stopped updating my blog posts. Follow-up blog posts. In order not to be overly divergent, let's take an unformed outline first, as shown below: Variable Life Cycle, type conversion PHP kernel exploration variable Variable Life Cycle, type conversion PHP Kernel

A year ago, due to the saturation of work, I was busy changing jobs, and I basically stopped updating my blog posts. Follow-up blog posts.

In order not to be too divergent, first create an unformed outline, as shown below:

1. PHPKernelExplorationOfVariableExtraordinary string
2. PHPKernelExplorationOfVariable VariableLife cycle and type conversion
3. PHPKernelExplorationOfVariable Variable(Foreach, in fact, the Zend part is more reasonable)
4. PHPKernelExplorationSAPI (why is it so reliable? )
5. PHPKernelExplorationFunctions (function implementation principle, user functions and system functions, and performance)
6. PHPKernelExplorationExtension (Extended lifecycle, basic extended processes, development frameworks, and simple extensions)
7. PHPKernelExplorationOpcode (Basic Principles of opcode, how to view opcode)
8. PhpKernelExplorationMemory Management (memory management model, API, zend MM, garbage collection GC)
9. PhpKernelExplorationObject-oriented
10. PHPKernelExplorationLanguage engine ZendEngine/Hiphop/HHVM (the last two are unofficial)

For each part, it may take 1-2 articles to record the corresponding learning process, for example, the extended development part. Because of the wide range of things, it will be lengthy to use one article, therefore, it may be split into two or more articles.

Similarly, due to the urgent time, there will inevitably be errors in the text. For any errors in this series, please contact us.
