Status: Feedback

Operating System: Windows 7
PHP Version: 5.3.1

New Comment:
I'm facing a problem in tracking down various issues in a complex project, and
I would greatly benefit from ability to call Exception::getTraceAsString()
statically.
So that instead of doing something like
default:
if(isset($GLOBALS['toolDebugfilterEnabled']) &&
$GLOBALS['toolDebugfilterEnabled'] === true)
{
print('Breakpoint reached in: ');
$e = new Exception($mode);
print($e->getTraceAsString());
I could just do a
default:
if(isset($GLOBALS['toolDebugfilterEnabled']) &&
$GLOBALS['toolDebugfilterEnabled'] === true)
{
print('Breakpoint reached in: ');
print(Exception::getTraceAsString());
and be done with it.

You actually have to remove the try/catch to reproduce the problem. When you
catch the exception, no fatal error is raised and you can see the stack trace.
If
you don't catch the exception, the PHP engine raises an E_FATAL error which
cannot be trapped.
We use a shutdown hook and check for fatal errors so we can report the issue,
but
at that point there's no stack trace--just the file and line where the error
occurred. It would be nice to have a similar function to error_get_last() to
get
the stack trace, such as backtrace_get_last().

I do get a trace here using your reproduce script with PHP 5.3.4RC1. So what is
the problem?

An observation from me:
A stack trace is dumped in the event of a fatal error (depending on the error
reporting level); but it's only when an uncaught exception reaches the top of
the call stack without being handled that such an error occurs. If it is
caught, then it's not an uncaught exception and therefore not a Fatal error.

Description:
------------
Always shows stack trace when a Fatal error occurs without having to do always
something like this :
<?php
function test() {
throw new Exception;
}
try {
test();
} catch(Exception $e) {
echo $e->getTraceAsString();
}
?>
Reproduce code:
---------------
<?php
function test() {
throw new Exception;
}
try {
test();
} catch(Exception $e) {
echo $e->getTraceAsString();
}
?>
Expected result:
----------------
#0 /home/bjori/tmp/ex.php(7): test()
#1 {main}
Actual result:
--------------
nothin'
