PHPStan vs. PT Application Inspector vs. Polyspace Code Prover vs. Python Comparison Chart

​PHPStan is an open source static analysis tool for PHP that identifies bugs in your codebase without the need for writing tests. It thoroughly scans your entire code, detecting both obvious and subtle issues, including those in rarely executed conditional statements that tests might not cover. By integrating PHPStan into your development environment and continuous integration pipelines, you can prevent bugs from reaching production. It is compatible with legacy codebases, even those lacking an autoloader, and facilitates gradual improvement through configurable rule levels. This approach allows developers to incrementally enhance code quality without being overwhelmed by numerous errors on the initial run. ​PHPStan supports advanced PHP features ahead of their official release, such as generics, array shapes, and checked exceptions, by leveraging PHPDocs. It also offers extensions for popular frameworks like Symfony, Laravel, and Doctrine, ensuring comprehensive understanding.

Polyspace Code Prover is a static analysis tool designed to prove the absence of critical runtime errors in C and C++ code without executing it. By utilizing formal methods, it analyzes all code paths and input scenarios to identify potential issues such as overflows, divide-by-zero errors, and out-of-bounds accesses. It provides insights into variables' ranges and identifies unreachable code, helping developers optimize software performance and ensure quality. Polyspace Code Prover supports safety standards like IEC 61508, ISO 26262, and DO-178C, making it suitable for industries requiring rigorous software certification.
