PHP Tip: More useful explode with item list

#php #shorttip #webdev #beginners

Securely, you did some item list like this once, didn't you?:

<?php function to_array(string $allowed_extensions): array { $allowed_list = explode(',', $allowed_extensions); return array_map(fn($ext)=> trim($ext), $allowed_list); } to_array('.pdf, .odt, .doc'); //['.pdf', '.odt', '.doc']
Enter fullscreen mode Exit fullscreen mode

not bad, but this is better:

<?php function to_array(string $allowed_extensions): array { $allowed_list = str_word_count($allowed_extensions, format: 1, characters: '.'); return array_map(fn($ext)=> trim($ext), $allowed_list); } to_array('.pdf, .odt, .doc'); //['.pdf', '.odt', '.doc']
Enter fullscreen mode Exit fullscreen mode

Why?, because now you can change list format without changing nothing more. Look!:

to_array('.pdf|.odt|.doc'); //['.pdf', '.odt', '.doc'] to_array('.pdf;.odt;.doc'); //['.pdf', '.odt', '.doc']
Enter fullscreen mode Exit fullscreen mode

Happy coding!
