Laravel Fluent isEmpty and isNotEmpty Methods

The Fluent class now includes isEmpty() and isNotEmpty() methods for checking whether an instance contains data.

Previously, checking if a Fluent instance held any data required indirect approaches:

use Illuminate\Support\Fluent;
 
$fluent = new Fluent(['name' => 'Laravel News']);
 
if (count($fluent->toArray()) > 0) {
    // Has content
}
 
if (isset($fluent->name) || isset($fluent->url)) {
    // Has some content
}

The new methods provide direct boolean checks:

$populated = new Fluent(['name' => 'Laravel News', 'url' => 'https://laravel-news.com']);
$empty = new Fluent();
 
$populated->isEmpty();    // false
$populated->isNotEmpty(); // true
 
$empty->isEmpty();        // true
$empty->isNotEmpty();     // false

Configuration processing shows practical usage:

use Illuminate\Support\Fluent;
 
class ConfigurationProcessor
{
    public function processSection(Fluent $config)
    {
        if ($config->isEmpty()) {
            return $this->getDefaultConfiguration();
        }
 
        return $this->buildConfigurationArray($config);
    }
 
    public function mergeConfigurations(array $sections)
    {
        $merged = new Fluent();
 
        foreach ($sections as $section) {
            if ($section->isNotEmpty()) {
                $merged = $merged->merge($section->toArray());
            }
        }
 
        return $merged->isNotEmpty() ? $merged : $this->getDefaultConfiguration();
    }
}

The methods work for conditional logic without array conversion:

if ($configData->isNotEmpty()) {
    $this->processConfiguration($configData);
} else {
    $this->loadDefaultConfiguration();
}

These methods eliminate the need to convert Fluent instances to arrays or check individual properties just to determine if the instance contains any data.
