I notice that you could get a notification due to the IDE requesting to pause the current request. How do I get to tell the server to pause the current request using the DbgListener component?

During debug session DbgListener calls IDbgSite::IsAlive()
By replying S_OK in IDbgSite::IsAlive(), the IDE confirms it's still ok (so didn't crash), by replying S_FALSE the IDE requests to pause. Please note, you don't need to return any E_xxx codes. COM RPC does it automatically if there is a problem with interprocess communications.

Let me see if I understand correctly:

- The IDE says pause the debug session
- I start returning S_FALSE on IDbgSite::IsAlive()
- Dbg will call HandleBreakpoint with reason BR_DEBUGGER_REQ

Correct?

- the user clicks PAUSE
- IDE returns S_FALSE to dbglistener
- dbglistener informs DBG module to stop at the first appropriate location
- DBG stops at that and informs dbglistener in normal way, e.g. via HandleBreakpoint

What do you mean by the first appropriate location?

I'm trying to do this buy DBG never calls HandleBreakpoint.

The sample script I'm using is a for loop with an echo:

for ($a = 0; $a < 100000; $a++)
echo "Test<br>";

is the problem that my script does not have an appropriate location for DBG to stop?

correct. You script does not. But the following does have



BTW, It's completely up to php itself to support such "locations"
