Previous Comments: ------------------------------------------------------------------------ [2012-02-26 12:05:42] clicky at erebot dot net jinmoku at hotmail dot com: Please read the report again. The documentation on the new operator (http://php.net/manual/en/language.oop5.basic.php#language.oop5.basic.new) states: "To create an instance of a class, the new keyword must be used. An object will always be created unless the object has a constructor defined that throws an exception on error." In the context of the "new" keyword, ONLY exceptions may be used to signal errors. In intl's case, "new" returns NULL on errors, which clearly is a bug per the documentation above, regardless of any INI setting the extension may otherwise provide to later change the way it signals errors. Sorry if I sound rude, but this bug has already been overlooked twice. Anyway, this bug will probably not be resolved any time soon due to stas' involvement with PHP 5.4. I'm slowly learning about core internals and will try to come up with a patch for this issue when I feel comfortable enough. ------------------------------------------------------------------------ [2012-02-21 10:20:52] jinmoku at hotmail dot com use the ini directive : intl.error_level ------------------------------------------------------------------------ [2010-09-04 23:23:04] clicky at erebot dot net Description: ------------ MessageFormatter's constructor returns NULL when an invalid pattern is given. Instead, it should throw an exception. This bug has already been reported twice before (see #52042 & #49161). Each time the report was marked as bogus because the real problem got overlooked. (the problem lies not in the given pattern being considered invalid by ICU, the problem is in the constructor returning NULL) Test script: --------------- <?php $f1 = msgfmt_create('en_US', '{this was made intentionally incorrect}'); echo 'f1 is ', gettype($f1), PHP_EOL; $f2 = MessageFormatter::create('en_US', '{this was made intentionally incorrect}'); echo 'f2 is ', gettype($f2), PHP_EOL; $f3 = new MessageFormatter('en_US', '{this was made intentionally incorrect}'); echo 'f3 is ', gettype($f3), PHP_EOL; ?> Expected result: ---------------- f1 is NULL f2 is NULL Fatal error: Uncaught exception 'Exception' with message 'Invalid pattern' in %s:%d. Actual result: -------------- f1 is NULL f2 is NULL f3 is NULL ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=52776&edit=1
