Problem: The application is susceptible to SQL injection attacks because user input is not properly handledSolution: An explanation by Fynix for detecting SQL injection vulnerabilities and suggesting the use of prepared statements

5. Cross-Site Scripting (XSS)

Issue: Cross-Site Scripting (XSS) attacks via insufficient input sanitizationSolution: Fynix detects unsanitized inputs and suggests security fixes

6. Performance Bottlenecks

Problem: The application is very slow due to inefficient codeSolution: Fynix identifies performance bottlenecks and recommends optimizations

7. Uncaught Exceptions

Problem: Poor exception management causes the app to crash.Solution: Fynix identifies missing try-catch blocks and recommends fixes

8. Hard-Coded Configuration

Problem: When configuration settings are hard-coded into code it is not flexibleAnswer: "In Fynix, configurations were extracted out from code to separate files for maintainability.

9. Poor Naming Conventions

Problem: Complexity and maintenance of the code due to poor naming conventionsSolution: Fynix produces reports on inconsistencies in order to enforce coding standards

10. Lack of Documentation

Problem: You have undocumented code that is not manageableA Solution: Fynix generates documentation with helpful comments

11. Unused Variables and Functions

Retention of unused code increases complexityFynix identifies unused functions and variables and suggests their removal in a matter of seconds.

12. Inconsistent Indentation

Problem: Irregular space between lines of code spoils readabilitySolution: Fynix automatically restructures code to ensure consistency

13. Missing Return Statements

Problem: Memory leaks due to inefficient resource usageSolution: Fynix tracks resource utilization and suggests optimizations

16. Hard-Coded Paths

Problem: Code that works on one machine will not possibly work on another machineSolution: Dynamic treatment recommendation after detecting hard coded paths

17. Inefficient Loops

Problem: Loops are not optimized efficiently, slowing down the performanceFind out more: Fynix analyzes loops and suggests optimizing

18. Error Suppression

Problem: It leads to unresolved issues by temporarily suppressing errors instead of addressing their root causesSolution: Fynix Identifies Suppressed Errors and Suggests Correct Handling

19. Direct Access to Superglobals

Problem: Unfiltered superglobal variables lead to security problemsThank you for your Interest and Visit: Fynix suggests proper ways of Validation and Filtering

20. Lack of Unit Tests

Problem: When it comes to unit tests, one of the significant problems we face is that there aren't enough.Problem: Code reliability isn’t guaranteed, leading to potential errors and bugs.
