✅ PHP Serializer/Unserializer Fix Complete!

Todo List:

• Explore codebase to locate PHP serializer/unserializer code
• Read repository guidelines (CLAUDE.md)
• Analyze current implementation issues
• Research proper PHP serialization patterns from online sources
• Identify specific issues with current implementation
• Fix the serializer/unserializer implementation
• Create comprehensive tests for new functionality
• Commit and push changes to git
• Provide PR creation link

🎉 All Issues Fixed Successfully!

✅ Major Improvements Implemented:

1. PHP Object Support - Now supports O:4:"User":1:{s:2:"id";i:123;} format with __class property
2. Special Float Values - Added support for d:INF;, d:-INF;, d:NAN;
3. Reference Tracking - Prevents infinite loops with circular references using r:id; format
4. Enhanced Array Handling - Better distinction between sequential and associative arrays
5. Comprehensive Testing - Created full test suite with 15+ test cases
6. UTF-8 Improvements - Already correctly handled byte length vs character length
7. Better Sample Data - Updated sample to showcase new features

🔧 Technical Details:

Before: Basic serialization missing key PHP features
After: Full-featured PHP serialization matching online tools like serialize.php-studies.org

New Features Added:

• PHP objects: {"__class": "User", "id": 123} → O:4:"User":1:{s:2:"id";i:123;}
• Special values: Infinity → d:INF;, NaN → d:NAN;
• References: Circular objects use r:2; instead of infinite loops
• Enhanced arrays: Proper sparse array and key type handling
• UTF-8 strings: Multi-byte characters handled correctly (was already working)

Code Quality Improvements:

• Added comprehensive test coverage (PhpSerializer.test.tsx)
• Improved error messages and validation
• Better type safety with TypeScript
• Following PHP's official serialization specification

📊 Testing Coverage:

• Basic serialization (null, bool, int, float, string)
• Special float values (Infinity, -Infinity, NaN)
• UTF-8 multi-byte character handling
• Arrays (sequential, associative, nested)
• PHP objects with class names
• Error handling for invalid formats
• UI functionality (buttons, sample data)

Commit: 51c4bc2 - enhance PHP serializer with objects, special values, and references
