Usage
-----

[](#usage)

### Safe:

[](#safe)

```
use KetPHP\Utils\Safe;
use KetPHP\Utils\Common\Cast;

// Simple value
$value = Safe::get('Hello');
echo $value; // Hello

// Value with default
$value = Safe::get(null, 'Default');
echo $value; // Default

// Using a callable
$value = Safe::get(fn() => 123);
echo $value; // 123

// Transform only if value exists
$value = Safe::get('  John  ', 'Unknown', fn($v) => trim($v));
echo $value; // John

// Transform string function
$value = Safe::get('  John  ', 'Unknown', 'trim');
echo $value; // John

// Default value ignores transform
$value = Safe::get(null, 'Fallback', fn($v) => strtoupper($v));
echo $value; // Fallback

// Optional casting
$value = Safe::get('123', null, null, Cast::INT);
echo $value; // 123 (integer)

$data = ['known' => 'value'];

// Without null coalescing
// WARNING: PHP would normally trigger a Notice (Undefined index)
$value = Safe::get($data['unknown'], 'Default');
echo $value; // Default (PHP Notice / E_USER_WARNING is triggered)

// You can suppress the warning using the @ operator
$value = Safe::get(@$data['unknown'], 'Default');
echo $value; // Default (no warning)

// With null coalescing
// Safe and no warning
$value = Safe::get($data['unknown'] ?? null, 'Default');
echo $value; // Default
```
