Package parallite-php
Short Description Execute PHP closures in true parallel using pcntl_fork — zero dependencies

FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package parallite-php
Features
- True Parallel Execution —
pcntl_forkruns closures in separate processes simultaneously - Zero Dependencies — only PHP 8.3+ with
ext-pcntlandext-posix(built-in) - No Daemon, No Binary — no external process to install, start, or manage
- No Closure Serialization — forked processes inherit parent memory; closures run as-is
- Simple async/await API — familiar Promise-like interface with global helpers
- Promise Chaining — chainable
then(),catch(), andfinally()methods - Cross-platform — fork mode on Linux/macOS, automatic sequential fallback on Windows
- Benchmark Mode — optional per-task metrics (execution time, memory, CPU)
Requirements
- PHP 8.3+
- ext-pcntl (Linux/macOS — built-in, enables fork mode)
- ext-posix (Linux/macOS — built-in, enables fork mode)
Windows? Parallite works on Windows in sequential fallback mode (no
pcntl_fork). Parallel execution requires a Unix-like OS.
Installation
That's it. No binary to download, no daemon to start, no post-install scripts.

Performance
Parallite provides significant speedup for I/O-bound and CPU-bound tasks:
| Tasks | Sequential | Parallel | Speedup |
|---|---|---|---|
| 3 × 1s | 3.0s | ~1.0s | 3.0x |
| 5 × 2s | 10.0s | ~2.0s | 5.0x |
| 10 × 1s | 10.0s | ~1.0s | 10.0x |
Example using the Filamentphp demo
Project with + 20 thousand orders, simulating several heavy calculations and with json transformation, as if it were for a heavy dashbaord (when I have time, I'll add this demo project to git):
✅ With Parallite:
🚫 Without Parallite:
The increase was approximately 321.4% in orders processed per second.
Real-World Example
Platform Support
| Platform | Status | Notes |
|---|---|---|
| Linux | ✅ Fully Supported | Fork mode (parallel) |
| macOS | ✅ Fully Supported | Fork mode (parallel) |
| Windows | ⚠️ Sequential Mode | No pcntl_fork — runs closures sequentially |
Troubleshooting

Quick tip: Use pd() inside async() calls — it throws an exception with the dump data.
How It Works
Parallite uses pcntl_fork() to create child processes that inherit the parent's entire memory space. This means:
- No closure serialization — closures run directly in the forked process
- No external daemon — each
async()call forks immediately - No startup overhead — fork is near-instantaneous (~0.1ms)
- Simple IPC — child writes result to a temp file, parent reads it on
await()
