Overview
--------

[](#overview)

A simple PHP class for singleton

Compatibility
-------------

[](#compatibility)

This library has been tested for PHP 7.3 and higher

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

[](#installation)

Just use composer in your project:

```
composer require lianhua/singleton

```

Usage
-----

[](#usage)

Create a class using \\Lianhua\\Singleton\\Singleton trait, that's all.

```
class MySingleton
{
    use \Lianhua\Singleton\Singleton;
    // Your methods and properties here
}
```

If you need a constructor, make sure it's a protected one

```
class MySingleton
{
    use \Lianhua\Singleton\Singleton;

    private $n;

    protected function __construct()
    {
        $this->n = 0;
    }
}
```

Upgrading
---------

[](#upgrading)

### From 1.0 to 2.0

[](#from-10-to-20)

Singleton became a trait instead of a class in order to create many singleton classes. Please edit your class like this:

**Then**

```
class MySingleton extends \Lianhua\Singleton\Singleton
{
    private $n;

    protected function __construct()
    {
        $this->n = 0;
    }
}
```

**Now**

```
class MySingleton
{
    use \Lianhua\Singleton\Singleton;

    private $n;

    protected function __construct()
    {
        $this->n = 0;
    }
}
```
