slugify

This method converts the string into a URL- and file-safe slug. It normalizes characters by stripping accents, converts everything to lowercase, replaces all non-alphanumeric characters with a given separator (defaulting to -), collapses multiple consecutive separators, and trims the separators from the start and end of the string.

It behaves similarly to toKebabCase, but is much stricter and designed for creating safe identifiers, making it ideal for URLs, file names, user handles, database keys, and SEO purposes.

Usage

$string = 'Olá mundo, como vai?';
$string = SM::slugify($string);
// or
$string = SM::make($string)
    ->slugify();
echo $string; // ola-mundo-como-vai

With a Custom Separator

You can optionally provide a custom separator to be used instead of a hyphen.

$string = 'Olá mundo, como vai?';
$string = SM::slugify($string, '_');
// or
$string = SM::make($string)
    ->slugify('_');
echo $string; // ola_mundo_como_vai
