PHP 5 to PHP 7 transpiler

Question

I have a big project in php 5 and it's well documented. Now, I want to migrate to php 7.2 and I have already checked the compatibility using phpstan and every thing is alright. So, I wonder if there is a tool that could automatically transform the php 5 annotations to php 7 (like functions declarations and variables )?

Thanks in advance

Can you show examples of what you want to convert. Annotations aren't something which I would have thought are directly related to the version of PHP. — Nigel Ren, Jun 01 '21 at 09:41

Aside from php-cs-fixer, also have a look at Rector. It offers much more advanced rules and allows you to create your own.

If you are looking to convert phpdoc param types to typehints, you can use php-cs-fixer that includes this kind of feature : phpdoc_to_param_type

There is also a fixer for function return types : phpdoc_to_return_type

Example from the php-cs-fixer documentation :

<?php

/** @param string|null $bar */
function my_foo($bar)
{}

will become

<?php

/** @param string|null $bar */
function my_foo(?string $bar)
{}

beware, those features are tagged as experimental so you should always double check what has been done.

Thanks man. This is kind of what I am looking for. So I will try it. Is there any thing like that for variables? — Ahmed, Jun 01 '21 at 11:57
