Enable Flexible Pattern Matching with Laravel's Case-Insensitive Str::is Method

Laravel enhances string pattern matching by adding case-insensitive support to the Str::is method, providing more flexible and user-friendly string comparisons with wildcard patterns.

The enhanced Str::is method accepts a third parameter for case-insensitive matching:

use Illuminate\Support\Str;
 
// Simple string matching
Str::is('Admin', 'admin', true); // true
 
// Wildcard pattern matching
Str::is('*.jpg', 'photo.JPG', true); // true
 
// Prefix matching
Str::is('SKU123*', 'sku12345', true); // true
 
// Custom patterns
Str::is('prd-001*', 'PRD-001-XYZ', true); // true
 
// Email matching
Str::is('JOHN.DOE@example.com', 'john.doe@example.com', true); // true

This enhancement proves particularly valuable in content management systems:

class AssetManager
{
    protected array $imageFormats = ['jpg', 'png', 'gif', 'webp'];
 
    public function validateAsset(string $filename)
    {
        foreach ($this->imageFormats as $format) {
            if (Str::is("*.{$format}", $filename, true)) {
                return true;
            }
        }
 
        return false;
    }
 
    public function processMediaUploads(array $files)
    {
        return collect($files)->filter(function ($file) {
            // Match media-specific files (e.g., MEDIA-*.*)
            return Str::is("MEDIA-*.*", $file, true);
        });
    }
 
    public function categorizeAsset(string $filename)
    {
        $categories = [
            'thumbnail' => 'THUMB-*.*',
            'banner' => 'BNR-*.*',
            'logo' => 'LOGO-*.*'
        ];
 
        foreach ($categories as $type => $pattern) {
            if (Str::is($pattern, $filename, true)) {
                return $type;
            }
        }
 
        return 'general';
    }
}

The case-insensitive option in Str::is creates more robust pattern matching by eliminating case sensitivity concerns, making applications more user-friendly while maintaining the powerful wildcard functionality.
