PHP Unserialize is a free online tool for decoding and visualizing PHP serialized strings. PHP serialization converts complex data structures like arrays and objects into a storable string format, and this tool reverses that process to show you the original data structure.
Our tool supports multiple input formats including PHP serialized strings, JSON data, and Base64-encoded content. The interactive tree view makes it easy to explore nested data structures of any complexity.
Whether you're debugging WordPress options, analyzing session data, or working with cached data, our tool provides instant visualization with multiple output formats. All processing happens in your browser, ensuring your data remains private.
Copy and paste your PHP serialized string, JSON data, or Base64-encoded content into the input area. The tool auto-detects the format.
Choose from multiple output formats: print_r for readable output, var_dump for type information, var_export for valid PHP code, or tree view for interactive exploration.
Click the Unserialize button to decode your data. The result will appear in the output panel with your selected format.
Use the interactive tree view to expand and collapse nested structures. Copy the output or switch between formats to analyze your data.
