Common questions
Frequently Asked Questions
How do I convert PHP to Kotlin?
Paste your PHP code into the input box, confirm the languages are set to PHP and Kotlin, and click Convert. CodeConvert AI analyzes your PHP code and generates equivalent Kotlin code in seconds, preserving the original logic and structure.
What are the main differences between PHP and Kotlin?
PHP and Kotlin differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each PHP construct to its closest Kotlin equivalent. See the comparison table below for the key differences between PHP and Kotlin.
Is the converted Kotlin code accurate?
The AI produces high-quality Kotlin code that preserves the behavior of your original PHP code and follows Kotlin conventions. It handles common patterns, data structures, and idioms for both PHP and Kotlin. For large or performance-critical code, review and test the Kotlin output before using it in production.
Can I convert an entire PHP project to Kotlin?
You can convert PHP files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from PHP to Kotlin. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
