Bug description:Remove inconsitency of internal exceptions and user defined
exceptions
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
