Well, considering the fact that PHP post v4 is trying to become Java, it made sense that at some point it would be able to run on the JVM or its step-cousin CLR.
By the way, does anyone know of a similar project where the JVM is targeted instead?
"project zero" was an effort from ibm to run php on jvm, but it's been several years since anything was done (have to assume it's abandoned).
i remember in 2003 wondering if something to allow php to run on jvm would be useful/viable - couldn't convince too many folks in the local user group that the idea had any merit.
