Is there any relationship between WebSphere sMash and the php.net PHP runtime?
Not in terms of code sharing for the runtime. The core runtime (the PHP ‘virtual machine’, if you will) is implemented in Java for our PHP implementation and in C for php.net PHP. The same is true for ‘extension’ functions. Of course, both implementations can use existing PHP libraries implemented in PHP. For example, the Zend Framework. Note, however, that because of the currently missing base functions it’s unlikely that frameworks implemented in PHP will run as you would want them to today. As previously noted, IBM engineers are contributing tests back to the PHP project, which are directly consumable by the php.net PHP implementation. We have also spent some time working on the PHP Development Toolkit (PDT) at the Eclipse project, adding function to the PHP debugger to enable it to debug PHP code using the XDebug (dbgP) protocol. Our implementation, in fact, uses the XDebug protocol for it’s own debug capabilities.
