- str_starts_with, str_contains used instead of strpos === 0, strpos !== 0, strpos === false, strpos !== false

- symfony/polyfill-php80 installed to introduce the polyfill and support php7.3 using php8 functions
- symfony/polyfill-ctype installed to introduce ctype functions in case somebody doesn't have the ctype extension installed
