There are a lot of random (and seemingly unrelated) things going on in the code. If all that code is actually needed to reproduce please say so. If need please provide the minimal code to reproduce the problem.

To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2018-12-12 08:33:08] someone dot is dot alive at gmail dot com Description: ------------ Function has 2 arguments. 2nd has a default value. When calling a function it returns an fatal error instead passing second argument as a default value. Test script: --------------- Test case is available in zip https://www.jerc.si/wp-content/uploads/2018/12/php7.3.zip Contains: - index.php - init.php (load files) - PHPDemo/Utils.php (echo's few lines) - PHPDemo/TestConst.php (simple class instance) Short preview: public static function testInput(string $name, int $step = TestConst::STEP_1) Utils::testInput('abc 1'); Utils::testInput('abc 2', TestConst::STEP_2); Utils::testInput('abc 3'); Expected result: ---------------- Based on a code in ZIP file. "Hello world! abc 3 > 1 yes" Actual result: -------------- TypeError: Argument 2 passed to PHPDemo\Utils::testInput() must be of the type int, unknown given, called in D:\www\index.php on line 10 in D:\www\PHPDemo\Utils.php on line 6 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77287&edit=1
