Phalanger is compatible with full range of PHP applications. Since every version of PHP is specific in some way and PHP applications are using these differences; Phalanger is being tested with latest versions of many opensource and commercial PHP applications to achieve better compatibility and fix application-specific issues.

Because Phalanger compiles the whole source code of PHP application, it usually finds a few hidden syntactic or semantic errors. These must be fixed first.

For more examples of single Phalanger usages and its possibilities, please see Code samples.

Phalanger supports both, native PHP4 extensions and their updated managed reimplementation into .NET. Managed extensions are always preferred, since they allow to run 64bit, they are faster and safe.

Missing managed extensions can be implemented, if it is required. Proprietary extensions are available as a part of support plans.

Note native extensions don't run on Mono/Linux, since they are compiled for Win32 platform. The only way is to use managed extensions here.
