Sorry, I mixed up actual result and expected result. It should be the
other way round...
So actual result is expected result, and expected result is actual
result ;-)

Description:
------------
Exceptions thrown by standard PHP classes are handled inconsistently to
user defined exceptions, but should not.
An internal exception, like the one thrown by DateTime::__construct()
when supplying and invalid date string (like '9999-11-33') also trigger
a E_WARNING.
User defined Exceptions do not trigger an additional E_WARNING.
If you create a custom error handler which converts all PHP errors to
exceptions, catching internal exceptions inline therefore throws another
Exception in the custom error handler, making it impossible to really
catch the Exception.
REQUEST:
Both exception types should work consistently likewise, preferrably
without triggering an E_WARNING.
Or there should be means to distinguish an error triggered by an
internal exception from an actual error and provide data if the
exception was already handled/catched.
Test script:
---------------
<?php
//////////////////////////////////
// PHP INTERNAL EXCEPTION:
//////////////////////////////////
register_shutdown_function('shutdown');
$time = '9999-11-33'; // obviously invalid ;-)
$timeZone = new DateTimeZone('UTC');
try {
$dateTime = new DateTime($time, $timeZone);
} catch (Exception $e) {
var_dump('Exception:', $e->getMessage());
}
echo 'END' . PHP_EOL;
function shutdown()
{
$error = error_get_last();
var_dump('Error ', @$error);
}
?>
<?php
//////////////////////////////////
// USER DEFINED EXCEPTION:
//////////////////////////////////
register_shutdown_function('shutdown');
try {
throw new Exception('Foo Exception');
} catch (Exception $e) {
var_dump('Exception:', $e->getMessage());
}
echo 'END' . PHP_EOL;
function shutdown()
{
$error = error_get_last();
var_dump('Error ', @$error);
}
?>
Expected result:
----------------
Output DateTime::__construct() exception:
string(10) "Exception:"
string(105) "DateTime::__construct(): Failed to parse time string
(9999-11-33) at position 9 (3): Unexpected character"
END
string(6) "Error "
array(4) {
["type"]=>
int(2)
["message"]=>
string(105) "DateTime::__construct(): Failed to parse time string
(9999-11-33) at position 9 (3): Unexpected character"
["file"]=>
string(67)
"/home/jebner/Zend/workspaces/DefaultWorkspace7/sandbox/datetime.php"
["line"]=>
int(8)
}
Output user defined exception:
string(10) "Exception:"
string(13) "Foo Exception"
END
string(6) "Error "
NULL
Actual result:
--------------
Output DateTime::__construct() exception:
string(10) "Exception:"
string(105) "DateTime::__construct(): Failed to parse time string
(9999-11-33) at position 9 (3): Unexpected character"
END
string(4) "Error "
NULL
}
Output user defined exception:
string(10) "Exception:"
string(13) "Foo Exception"
END
string(6) "Error "
NULL
