#49497 [NEW]: No ability to supply a userland PHP function as a callback for a COM method.

From: RQuadling at GMail dot com Operating system: Windows XP SP3 PHP version: 5.3SVN-2009-09-08 (snap) PHP Bug Type: COM related Bug description: No ability to supply a userland PHP function as a callback for a COM method. Description: ------------ Hi. I think I'm pretty much on my own here, but here goes. I'm evaluating a COM tool to allow me to OCR documents. The COM object requires the registration of a callback to allow the object to send results as it finds them (events in their terminology) back to a handler for processing (say logging in a DB, etc.). According to their documentation, in C and VB, the registration is a trivial process of simply supplying the address of the function as the handler for the callback. Obviously, this won't work in PHP as a PHP function isn't accessible like a compiled function from outside of PHP. The "value" to be supplied is of type VT_I4. This is essentially just the address of the function (as I see things). So, I think that a proxy is needed. Something to act in the middle of the PHP script and the callback invocation by the COM object.
