PHP Version Transpiler
======================

[](#php-version-transpiler)

Remove PHP7 language features and add PHP 5.6 compatible syntax :)

Install:

```
composer require janpiet/php-version-transpiler

```

Usage:

```
_Bin_Path/_php-version-transpiler _PHP_7_Source_Directory_ _PHP_5_6_Target_Directory_

```

Run tests:

```
composer install
bin/phpunit

```

View the files it generates:

- Input: `tests/_fixtures`
- Output: `tests/_out`

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

[](#installation)

requires composer & php7

```
composer install
bin/phpunit

```

Support
-------

[](#support)

As with every solution to such a problem there is no way to solve erverything, and there is no way to solve everything with one thing. I suspect there will far more use cases for a Shim for many incompatibility between 5.6 and 7.0. Other stuff will be that hard to detect, that I am not sure it will be worth it. Especially some of the more subtle additions to the language will not be emaulatable. But maybe they are not worth pursuing either?
