Convert PHP5 code to PHP7 (scalar type hinted parameters, return types)

php5to7

Convert PHP5 code to PHP7 (scalar type hinted parameters, return types) by reading the PHPdoc blocks of your source file. For example, in PHP5 code if you had @param int $index, the function signature will be modified as public function myFunc(int $index) {

Usage

(Not in packagist yet) Clone/download this repository and install the dependencies using composer.

composer install

Usage:
php php5to7.php [OPTIONS] <file/directory>

--overwrite     Instead of outputting the changed source, writes
                the php7 changes into the file.
--backup        For every file it modifies, copies the original
                to filename.php.bak.
-h  --help      This help message.

<file/directory> The path to the individual file, or a directory
                 to process every php file recursively.

Limitations & Risks

This should not be used for large projects, mission critical code, etc. This is currently an on-going experiment.

• No typehinting will be done on:
• Parameters that are not documented with PHPdoc blocks
• Parameters that are more than one type, e.g. string|array
• Parameters other than the basic scalars: int, float, string, and bool
• Code with scalar typehints may operate slower than code without them (might be negligible)
