correlate-php-core
==================

Overview
--------

[](#overview)

It's very difficult to track a request accross the system when we are working with microservices. We came out a solution for that. We generate a unique version 4 uuid for every request and every service passes this id via request header to other services. We call this **correlation ID**.

Packages
--------

[](#packages)

- [proemergotech/correlate-php-laravel](https://github.com/proemergotech/correlate-php-laravel)
    - Middleware for Laravel and Lumen frameworks.
- [proemergotech/correlate-php-psr-7](https://github.com/proemergotech/correlate-php-psr-7)
    - Middleware for any PSR-7 compatible frameworks like [Slim Framework](https://www.slimframework.com/).
- [proemergotech/correlate-php-monolog](https://github.com/proemergotech/correlate-php-monolog)
    - Monolog processor for correlate middlewares (you don't have to use this directly).
- [proemergotech/correlate-php-guzzle](https://github.com/proemergotech/correlate-php-guzzle)
    - Guzzle middleware to add correlation id to every requests.
- [proemergotech/correlate-php-core](https://github.com/proemergotech/correlate-php-core)
    - Common package for correlate id middlewares to provide consistent header naming accross projects.

Installation
------------

[](#installation)

You should not use this directly.

By the way if you want to use it directly, you can install it via composer.

```
$ composer require proemergotech/correlate-php-core
```

Defaults
--------

[](#defaults)

Default header name is `X-Correlation-ID` and default parameter name is `x_correlation_id`.

Usage
-----

[](#usage)

Generate a correlation id:

```
\ProEmergotech\Correlate\Correlate\Correlate::id();
```

Other methods:

```
\ProEmergotech\Correlate\Correlate::getHeaderName();
\ProEmergotech\Correlate\Correlate::getParamName();
\ProEmergotech\Correlate\Correlate::getGeneratorFunc();

// You can override defaults...
\ProEmergotech\Correlate\Correlate::setHeaderName('X-My-Correlation-ID');
\ProEmergotech\Correlate\Correlate::setParamName('my_correlation_id');
\ProEmergotech\Correlate\Correlate::setGeneratorFunc(function(){
  return uniqid();
});
```
