How do I convert PHP code to C# (CS) using this tool?

Paste your PHP source into the left panel, select C# (CS) as the target format, and click the Convert button. The converter automatically translates PHP constructs—like foreach loops, associative arrays, and class methods—into their C# equivalents. After conversion, you can copy the generated C# code from the right panel and add the necessary using directives (e.g., System.Collections.Generic) and namespace declarations to fit your .NET project.

Why should I convert PHP to C# instead of rewriting manually?

Converting PHP to C# brings your application into the .NET ecosystem, which offers superior runtime performance, static typing for early error detection, and seamless integration with Azure, LINQ, and Entity Framework. Automated conversion reduces manual effort, preserves business logic, and provides a consistent starting point for further modernization—especially when porting WordPress plugins or legacy PHP systems to ASP.NET Core.

How are PHP dynamic types and arrays handled in the conversion?

The converter infers C# types from PHP usage: strings become string, integers become int, and arrays are mapped to List or T[] based on key structure. When a type cannot be determined statically, it uses dynamic or object and adds a TODO comment for manual review. Associative arrays are converted to Dictionary , and PHP's mixed function parameters become dynamic in C# to ensure compatibility. This preserves runtime behavior while allowing you to optimize types later.
