PHPDBG

问题 Since I still have troubles with PHPUnit / PHP Code Coverage and Xdebug, I decided to try it another way -- with phpdbg. I did it as hier shown. Tried in CMD and also in Git Bash, but the result is the same, it fails: $ composer info | grep "phpunit" phpunit/php-code-coverage 4.0.0 Library that provides collectio... phpunit/php-file-iterator 1.4.1 FilterIterator implementation t... phpunit/php-text-template 1.2.1 Simple template engine. phpunit/php-timer 1.0.8 Utility class for timing phpunit

问题 I'm trying to remove the STDIN constant for debugging purposes, however phpdbg> ev runkit_constant_remove('STDIN') [PHP Warning: runkit_constant_remove(): Only user defined constants may be removed. in eval()'d code on line 1] So I would like to know whether there exists any way in php to remove these non-user constants. 来源： https://stackoverflow.com/questions/31315783/remove-non-user-constant-php
