Add Multiple Built-in Validation Attributes

[Copilot]

This PR adds a comprehensive set of built-in validation attributes to reduce the need for custom rule implementations for common validation scenarios.

Added Validation Attributes

Basic Constraints:

• Required - Field must be present (but can be empty)
• NotEmpty (existing) - Field must be present and not empty

String Constraints:

• MaxLength - Limits string length to a specified number of characters
• MinLength - Ensures string has at least a specified number of characters

Numerical Constraints:

• Min - Ensures numeric value is greater than or equal to specified minimum
• Max - Ensures numeric value is less than or equal to specified maximum
• Between - Ensures numeric value is within a specified range

Format Constraints:

• Email - Validates correct email format
• Url - Validates correct URL format
• Regex - Allows custom regex pattern validation

Collection Constraints:

• Each - Applies a validator to each element in an array

Implementation Details

All attributes:

• Extend BaseValidatorAttribute
• Implement the ValidatorAttributeInterface
• Include appropriate validation logic in their validate() method
• Support custom error messages

Example Usage

class UserModel 
{
    #[Required]
    #[NotEmpty]
    #[MaxLength(50)]
    public string $name;

    #[Email]
    #[Required]
    public string $email;

    #[Min(1)]
    #[Max(100)]
    public int $age;
}

Documentation

• Updated README.md with examples and details for all new validation attributes
• Added comprehensive tests for each validation attribute

Fixes #19.

Warning

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.github.com
  • Triggering command: /usr/bin/php8.3 -n -c /tmp/z6uqU1 /usr/bin/composer install (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list

php's empty() function considering zero as empty value so the NotEmpty atribute will return wrong validation. Can you fix it?

[Copilot]

Fixed in commit 5b953f7. Changed the NotEmpty validator implementation from using PHP's empty() function to explicit checks for null and empty string only. Now integer 0 is correctly treated as valid (not empty).

You testing here length of string not the value itself... as few lines above you returning false when the length is numeric.

[Copilot]

Fixed in commit 6bb7661. Changed the numeric validators (Min, Max, Between) to use is_int($value) || is_float($value) instead of is_numeric($value) to only accept actual numeric types, not string representations. This ensures consistency with the test expectations where string values like '7' should be rejected.

@copilot can you also add docblock to other validators you created?

@copilot can you also add docblock to other validators you created?

Added comprehensive docblocks to all validation attributes in commit 5fd386b. Each validator now includes class-level documentation, constructor parameter details, and validate method documentation.
