PHP Trans-Porter

PHP Trans-Porter is a small utility that trans-ports (get it...?) source code from one PHP version to be used in another.

As someone that does freelance work from time to time, but has a limited amount of it, I became really frustrated with clients' hosting requirements varying between the different PHP versions available (PHP 5.6 to PHP 7.1 and up), and not being able to use new language features (e.g. scalar type hinting) and the potential performance benefits they provide.

Since its sometimes not possible for a client to update their hosted version of PHP (due to multiple, but sometimes questionable reasons :) ), I needed to find a way to stream-line my work-flow so that:

• I could waste less time trying to convince my clients to upgrade or change hosts,
• use the newest PHP language features,
• and spend less time explaining version-specific bugs that pop up every-so-often, when you're juggling versions.

Features

PHP Trans Porter currently features back-porting for PHP versions 5.6, 7.x (7.0 to 7.2), as well as bulk transformations (specify an input directory and an output directory, and all .php files will be converted recursively).

The utility tries to make the least amount of changes possible, but with the goal of generating source code that should not have to be modified again.

The current base version is: PHP 8.2.

Conversion features for PHP 7.3 and above:

• None (yet!)

Conversion features for PHP 7.2 to PHP 7.1:

• Remove instances of the 'object' type from return type-hints, as well as from parameter type-hints and casts.
• Remove scope modifiers (private, protected or public) from class constant definitions.

Conversion features for PHP 7.1 to PHP 7.0:

• Remove instances of the 'void' return type.
• Remove instances of nullable returns types (e.g. '?int'), as well as from parameter type-hints.

Conversion features for PHP 7.0 to PHP 5.6:

• Remove all scalar type-hints ('bool,' 'float,' 'string' and 'int') from return- and parameter type-hints.
• Include a 'use' statement that references '\Exception' aliased as 'Throwable.'

All conversions stack up - thus, converting from PHP 7.2 to PHP 5.6, will first it to 7.1, then 7.0 and finally 5.6.
