> Average variable name length in popular PHP projects
## Introduction
This project show the average length of [variable](http://php.net/manual/en/language.variables.php)
names of [the Top 30 (by ammount of stars) PHP projects on Github](https://github.com/search?l=php&q=language%3APHP&s=stars&type=Repositories).
The logic that is used to retrieve these values has been included as [a separate shell script](variable-names-length-per-php-project.sh).
