Unfortunately, I need to keep scalars/arrays in the frame too. But thinking along your line, do you know of a function that does a similar thing to the function call itsself ? ( as functions get stacked, called recursive or through callback mechanisms, there must be a similar allocation table/mechanism as for variables/objects) Regards, Bert -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] error_handler : unique caller ID ?
Dear list,
a penny for your thoughts on the following problem.
Does anyone have an idea how to find a unique caller ID for a
user-defined error handler ?
The goal is to get a cached error messages tree where the following
snippet would yield an array as below it:
// start-of-snippet
function Outer($a)
{
trigger_error('entering Outer');
$a=Inner($a) ;
trigger_error('leaving Outer') ;
}
function Inner($x)
{
trigger_error('entering Inner');
return(2*$x) ;
}
trigger_error('Here we go ');
$b = 1 ;
$b = Outer($b) ;
trigger_error('End result is $b');
// end-of-snippet
Output:
Array(
[0] = 'Here we go'
['Outer(unique_ID_01)'] = Array(
[0] = 'entering Outer' ;
['Inner(unique_ID_02)'] = Array(
[0] = 'entering Inner' ;
)
[1] = 'leaving Outer' ;
)
[1] = 'End result is 2'
)
I've considered the 'args' option in debug_backtrace(), but that fails
for referenced arguments.
Having read access to a variable's address (like a C-pointer) would be
perfect - but Google tells me you can't in PHP.
Any other idea's ?
Regards,
Bert
