version 4.5.0 is not compatible with PHP 7 although mentioned in packagist about slugify HOT 3 OPEN

For people affected by this, a better workaround is adding this to your composer.json:

    "conflict": {
        "cocur/slugify": "4.5.0"
    },

Doing so, will allow your project to fetch later versions, once you get around to bumping it to PHP 8.x.

Idem with PHP 7.1 with tag 4.5.0 :

syntax error, unexpected 'array' (T_ARRAY), expecting function (T_FUNCTION) or const (T_CONST) in /var/www/html/vendor/cocur/slugify/src/Slugify.php:34

protected array $rules = [];

I had to write in my composer.json "cocur/slugify": "~4.4.0", to downgrade to 4.4.0 and fix it
