One of the most anticipated features in PHP 8 is the new just in time (JIT) compiler, which adds the performance benefits of caching of compiled code to the traditionally interpreted language. But do these performance expectations match the applied reality?
Learn More About the New JIT Compiler in PHP 8
Join Zend Product Manager and Principal Engineer, Matthew Weier O’Phinney, as he discusses the level of benefit (and complexity) developers can expect in real-world PHP applications using JIT compilation, including discussions on:
- How the new JIT compiler works.
- How JIT compilation will impact PHP application performance.
- Potential issues developers may experience while using JIT compilation.
- How JIT compilation may open the door for new language features and approaches
- And more!
