PHP Expression Language based on TWIG
This library provides interfaces for safe evaluate expressions, compile them to native PHP code for performance.
Purpose
It is an alternative to the Symfony Expression Language which allows more operations such as for if etc.
You can to implement any logic and execute it safely and quickly. We removed PRINT_TOKEN TEXT_TOKEN from
TWIG AST-tree to prevent output, added return statement and made a more improvement.
Features
- Allow to execution scripts and evaluate expressions.
- Debugging with PhpStorm twig debugger feature.
- Support all twig features, like sandbox, custom extension, tokens, functions.
- Minimum performance overhead - faster that twig.
- Syntax highlighting is already built into the most popular IDEs.
Example Usage
Base evaluate Example
Execute Script
evaluate method - is faster than execute, because we skip additional exception handling and error logic.
Also evaluate - accept code without {% token.
Benchmark Test
We use next the test to compare overhead between Symfony Expression Language and this library
Extends and sandbox mode.
Result
| Lang | Op. Time | Overhead cost |
|---|---|---|
| Native PHP | 0.058µs | 0% |
| Symfony EL | 0.461µs | +800% |
| Twig lang | 0.187µs | +300% |
