Modify src/Snps/IO/Reader.php with contents:
• Update the namespace declaration to ensure it matches the current structure of the PHP project.
• Replace the use of Python-specific libraries (e.g., pandas, numpy) with PHP equivalents or custom implementations. For data manipulation, consider using arrays or collections from libraries like Laravel Collections. For numerical operations, explore MathPHP.
• Convert Python functions and method calls into their PHP equivalents, paying close attention to differences in syntax and functionality. This includes file I/O operations, string manipulation, and data processing.
• Adapt the logic for interacting with external resources, such as the Ensembl REST API, to use PHP's HTTP client libraries (e.g., GuzzleHttp).
• Ensure that the class structure and method signatures are idiomatic PHP, using visibility keywords (`public`, `private`, `protected`) appropriately and typing method parameters and return types.
• Implement error handling using PHP's exception mechanism, replacing Python's `try-except` blocks with `try-catch` blocks in PHP.
• Add comprehensive PHPDoc comments to methods and properties to improve code readability and support IDE features like auto-completion.

Modify src/Snps/IO/ExtraTabsFilter.php with contents:
• Create the `ExtraTabsFilter.php` file to define a custom stream filter for handling extra tabs in CSV files, similar to the Python implementation.
• Define a class `ExtraTabsFilter` that extends PHP's `php_user_filter`.
• Implement the `filter` method to process each line of input, removing or replacing extra tabs as necessary.
• Register the filter using `stream_filter_register` in the constructor or initialization method of the `Reader` class.

Modify src/Snps/SNPsResources.php with contents:
• Ensure that the `SNPsResources` class provides methods for accessing and manipulating SNP resources, similar to the Python version.
• Implement methods for downloading, caching, and accessing SNP data files, adapting Python file I/O operations to PHP.
• Use the GuzzleHttp client for making HTTP requests to external APIs, replacing Python's requests library.
• Add methods for parsing and processing SNP data, converting Python data manipulation code into PHP.

Modify src/Snps/IO/CsvReader.php with contents:
• Create a `CsvReader` class to abstract the reading and parsing of CSV files.
• Implement methods for opening CSV files, setting options like delimiter and enclosure, and iterating over rows.
• Consider using PHP's built-in `fgetcsv` function for parsing CSV rows.
• Provide functionality for applying filters or transformations to the data as it is read, similar to the Python implementation's use of pandas DataFrames for data manipulation.
