DownloadGeneric Executor Service in PHP
A Generic Executor Service in PHP for asynchronous calls. 
This repository demonstrates a basic implementation of a Generic Executor Service in PHP 8 using the `pcntl` extension to handle concurrency. It mimics the behavior of Java's ExecutorService by managing a pool of "workers" (processes) that execute tasks asynchronously. 
generic-executor-service-php a language port from Java to PHP from the repository which I created a while ago called generic-executor-service-java (https://github.com/niteshapte/generic-executor-service-java) 
Features
- 
Task Submission: Submit tasks (callables) to be executed asynchronously by the worker pool.
 
- 
Worker Pool Management: Limit the number of concurrent workers (processes) executing tasks.
 
- 
Graceful Shutdown: Waits for all tasks to complete before shutting down.
 
 
Requirements
Installation
Clone the repository: git clone https://github.com/your-username/generic-executor-service-php.git
cd generic-executor-service-php
 Ensure you have `pcntl` enabled in your PHP environment. 
Run the script using the PHP CLI: php executor.php
 
Handling Concurrency with `pcntl`
The `GenericExecutorService` relies on the `pcntl_fork()` function to create separate processes for each task. This provides concurrency in environments where PHP doesn't natively support multi-threading. However, `pcntl` is only available in CLI and POSIX-compliant environments (Linux/macOS). 
Compatibility
## Customization
You can modify the following aspects of the service:
- Max Workers: Control the maximum number of concurrent workers by passing an integer to the GenericExecutorService constructor.
- Task Length: Simulate longer or shorter tasks by adjusting the sleep duration inside the tasks.
