- Installation request for phpclasses/php2wsdl >=0.5 -> satisfiable by phpclasses/php2wsdl[0.5].
- phpclasses/php2wsdl 0.5 requires wingu/reflection ~1.0 -> no matching package found.
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
