# WPupdatePHP library
Library to be bundled with WordPress plugins to enforce users to upgrade their PHP versions _or_ switch to a decent host.

## Installation
We recommend installing the library using [Composer](https://getcomposer.org/), as follows.

```
composer require wpupdatephp/wp-update-php
```

Another option is to download the [class file](https://github.com/WPupdatePHP/wp-update-php/blob/master/src/WPUpdatePhp.php) manually.

## Usage
Usage of this library depends on how you start your plugin. The core `does_it_meet_required_php_version` method does all the checking for you and adds an admin notice in case the version requirement is not met.

For example, when you start your plugin by instantiating a new object, you should wrap a conditional check around it. 

_Example:_

```php
$updatePhp = new WPUpdatePhp( '5.4.0' );

if ( $updatePhp->does_it_meet_required_php_version() ) {
    // Instantiate new object here
}

// The version check has failed, an admin notice has been thrown
```

## Including the library file
Adding the library via Composer has preference. The Composer autoloader will automatically take care of preventing including two classes with the same name.

In case you want to include the file manually, please wrap the include or require call in a [`class_exists`](http://php.net/class_exists) conditional, like so:

```php
if ( ! class_exists( 'WPUpdatePhp' ) ) {
	// do the file include or require here
}
```

## Setting the name of the plugin
The notice that will be thrown can also contain the name of the plugin. Use the `set_plugin_name( $name )` method on the `WPUpdatePhp` object to provide the name. This call needs to be made before the `does_it_meet_required_php_version()` method is called to check versions.
