DPC2019: Crazy Fun Experiments with PHP (Not for Production) - Zan Baldwin

PHP streams and stream wrappers

• Streams are a fundamental aspect of PHP development, enabling input/output operations
• PHP cores supports several protocols: file, https, ftp, ssh, etc.

Aspect-Oriented Programming (AOP)

• AOP is a framework for developing PHP applications using metaprogramming
• It allows modifying the behavior of classes and methods at runtime

Generating code on the fly

• Use a code template to generate valid PHP code
• Demonstrate how to use a stream filter to modify the code before execution

Auto-loader overloading

• Discuss the auto-loader overloader, which hijacks the normal composer logic
• Use it to generate code on the fly and register it with PHP

Encrypted source code

• Discuss the example of encrypted source code and how it can be decrypted
• Use a simple encryption method to demonstrate the process

Streams and Stream Filters

• Explain how streams can be used to manipulate data as it passes through
• Discuss the use of stream filters to modify the stream data

Aspect-Oriented Programming (AOP) Techniques

• Discuss the use of AOP to interrupt the execution flow of code
• Explain how AOP can be used to add logic at specific points in the code

Error Handling

• Discuss how error handling can be achieved in AOP
• Explain how exceptions can be handled and caught using AOP

Metaprogramming

• Discuss the concept of metaprogramming and its relevance to AOP
• Explain how AOP enables metaprogramming in PHP
