# PHP vs. C Benchmarking System
This project provides a simple framework for benchmarking the performance of various functions in PHP against their equivalents in C.
## Benchmarked Functions
The following functions are included in this benchmark suite:
- `password_hash()` (using Argon2i, mem=32768, time=2, threads=1)
- `hash('sha256', ...)`
- `substr()`
- `gmp_init()`
- `gmp_mul()`
- `gmp_add()`
- `gmp_div()`
- `hexdec()`
- `time()`
- Date Math: Addition
- Date Math: Subtraction
- `microtime(true)`
## Requirements
- Ubuntu 22.04 (or a compatible Debian-based distribution)
- `git`
## Setup and Installation
1. **Clone the repository:**
```bash
git clone
cd
```
2. **Run the installer:**
The `install.sh` script will update your package manager and install all the required dependencies (`gcc`, `make`, `php`, `php-gmp`, `libgmp-dev`, `libargon2-dev`, `libssl-dev`, and `bc`).
```bash
./install.sh
```
## How to Run the Benchmarks
The benchmarking process is broken into two main scripts: `compile.sh` and `benchmark.sh`.
1. **Make the scripts executable:**
(This only needs to be done once.)
```bash
chmod +x compile.sh
chmod +x benchmark.sh
```
2. **Compile the C code:**
This script navigates to the `c/` directory, cleans any old binaries, and compiles all the C source files using the optimized flags specified in the `Makefile`.
```bash
./compile.sh
```
3. **Run the benchmark suite:**
```bash
./benchmark.sh [crypto_iterations] [fast_func_iterations]
```
- `[crypto_iterations]` is an optional argument for the number of iterations for slow cryptographic functions (e.g., `password_hash`). Defaults to `1000`.
- `[fast_func_iterations]` is an optional argument for the number of iterations for all other, faster functions. Defaults to `100000`.
**Example:**
```bash
# Run with default iterations
./benchmark.sh
# Run with 10 crypto iterations and 1,000,000 fast function iterations
./benchmark.sh 10 1000000
```
## How it Works
The `benchmark.sh` script performs the following actions:
1. **Executes Benchmarks:** For each function, it runs both the compiled C executable and the corresponding PHP script, passing the same set of parameters (input data and iterations).
2. **Collects Results:** It captures the execution time (in seconds) from the output of each script.
3. **Generates Report:** The results are saved in a CSV file at `results/benchmark_results.csv`. The script will also print the contents of this file to the console upon completion.
## C Binaries
You can compile the C binaries at any time by running the `./compile.sh` script or by running `make` inside the `c/` directory. The compiled binaries are committed to the repository.
