### Using the Str Class

[](#using-the-str-class)

```
use RomanLazko\Str\Str;

// Get string length
$length = Str::length('Hello World'); // 11

// Convert to kebab-case
$kebab = Str::kebab('fooBar'); // 'foo-bar'

// Convert to snake_case
$snake = Str::snake('fooBar'); // 'foo_bar'
// Convert to camelCase
$camel = Str::camel('foo-bar'); // 'fooBar'
// Convert to StudlyCase
$studly = Str::studly('foo_bar'); // 'FooBar'

// String manipulation
$reversed = Str::reverse('Hello'); // 'olleH'
$limited = Str::limit('This is a long string', 10); // 'This is a...'
$words = Str::words('This is a long string', 3); // 'This is a...'
```

### Using the str() Helper

[](#using-the-str-helper)

```
// Chainable string manipulation
$result = str('Hello World')
    ->upper()
    ->replace('WORLD', 'Universe')
    ->finish('!')
    ->toString();
// Result: 'HELLO UNIVERSE!'
```
