Step 1: 🔎 Searching

I found the following snippets in your repository. I will now analyze these snippets and come up with a plan.

Some code snippets I think are relevant in decreasing order of relevance (click to expand). If some file is missing from here, you can mention the path in the ticket description.

// You may need to find alternative libraries for numpy, pandas, and snps in PHP, as these libraries are specific to Python
// For numpy, consider using a library such as MathPHP: https://github.com/markrogoyski/math-php
// For pandas, you can use DataFrame from https://github.com/aberenyi/php-dataframe, though it is not as feature-rich as pandas
// For snps, you'll need to find a suitable PHP alternative or adapt the Python code to PHP
// import copy // In PHP, you don't need to import the 'copy' module, as objects are automatically copied when assigned to variables
// from itertools import groupby, count // PHP has built-in support for array functions that can handle these operations natively
// import logging // For logging in PHP, you can use Monolog: https://github.com/Seldaek/monolog
// use Monolog\Logger;
// use Monolog\Handler\StreamHandler;
// import os, re, warnings
// PHP has built-in support for file operations, regex, and error handling, so no need to import these modules

// import pandas as pd // See the note above about using php-dataframe or another PHP library for data manipulation
// from pandas.api.types import CategoricalDtype // If using php-dataframe, check documentation for similar functionality

Step 2: ⌨️ Coding

Modify src/Snps/SNPs.php with contents:
• Update the namespace declaration to match PHP 8.3 standards, ensuring it is at the top of the file following any opening `• Replace the Python-specific libraries and functionalities with their PHP equivalents or alternatives. For instance, use MathPHP for numerical operations instead of numpy, and create or find a suitable library for data manipulation similar to pandas. If a direct equivalent is not available, consider implementing the necessary functionality within the project.
• Convert Python class definitions, methods, and properties into PHP, ensuring to type all properties and method return types according to PHP 8.3 features. This includes using typed properties, arrow functions, and the nullsafe operator where applicable.
• Adapt file I/O operations from Python to PHP, utilizing PHP's built-in functions and classes for reading from and writing to files. This may involve modifying the `Reader` and `Writer` classes in the `src/Snps/IO` directory to ensure compatibility with the updated `SNPs.php` file.
• Implement any missing functionalities that are present in the Python version but not in the PHP version, such as specific SNP analysis methods or data manipulation operations. This may require creating new methods within the `SNPs.php` class or adding new helper classes/functions in the `src/Snps` directory.
• Ensure all modifications and new implementations are thoroughly documented, following PHPDoc standards for documenting classes, properties, and methods. This is crucial for maintainability and understanding of the codebase.
• After making the necessary changes, perform extensive testing to ensure the PHP version matches the functionality of the Python version. This includes unit tests for individual methods and integration tests for the overall SNP analysis functionality.
