A TypeError isn't a fatal error, though. Previous Comments: ------------------------------------------------------------------------ [2017-09-13 17:59:37] spam2 at rhsoft dot net that below is part of my fuzzy-call-suite for string params with work with 7.0/7.1/7.2 perfectly - you can catch fatal errors starzing with PHP 7.0 try { $params[] = $reflection_param->getDefaultValue(); } catch(Throwable $exception) { $params[] = bin2hex(random_bytes(5)); } ------------------------------------------------------------------------ [2017-09-13 17:22:21] cmb@php.net As of PHP 7.0.0 a TypeError is thrown, if the parameter is not a string, see <https://3v4l.org/DuLJt>. ------------------------------------------------------------------------ [2011-12-29 01:37:38] hanskrentel at yahoo dot de Description: ------------ Normally Instantiation fails (ReflectionException): $test = new ReflectionFunction(''); However this can be fooled: $obj = new stdClass(); $test = new ReflectionFunction($obj); echo $test; The echo line triggers a fatal error then: Fatal error: ReflectionFunction::__toString(): Internal error: Failed to retrieve the reflection object Before that happens there is a slightly misworded warning ahead: Warning: ReflectionFunction::__construct() expects parameter 1 to be string, object given Misworded in the sense that it's possible objects with __toString() and closures. Probably something in the logic inside the constructor is not right. It would be good if in such cases an ReflectionException is thrown on instantiation. Test script: --------------- $obj = new stdClass(); $test = new ReflectionFunction($obj); echo $test; Expected result: ---------------- ReflectionException Actual result: -------------- Fatal Error ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60620&edit=1
