I'm using the register_tick_function as follows:
<code>
function debugger_tick() {
global $debugger_trace;
$debugger_trace[microtime()] = debug_backtrace(TRUE);
}
</code>
Why the backtraces are always the same, from the place where I
registered function via register_tick_function() to that tick
function.
It's possible to get the backtrace of the executed code, not tick
function?
If not, are there any alternatives? Especially without adding any
additional PHP module

I'm not sure what you're asking for. debug_backtrace is showing the
tick function, which is the code being executed in this thread.

I just figure it out.
register_tick_function has completely different scope, so globals
aren't the same globals.
So the solution is to return the backtrace.
declare(ticks = 1);
register_tick_function('debugger_tick');
function debugger_tick($dump = FALSE) {
static $backtraces = array();
$backtraces[] = debug_backtrace(TRUE);
if ($dump) {
return $backtraces;
}
}
So every time when you need to access the backtraces, you need to pass
TRUE to the tick function.
$my_backtraces = debugger_tick(TRUE);
Probably _SESSION will work as well, but I'm not sure.
