PHP closure as static class variable

两盒软妹~` 提交于 2019-12-25 06:57:59
问题 I wanted to have a static closure variable in my class, so that people can change the behavior of a specific part of the code. However, I can't seem to be able to initialize it anywhere. First I tried this: public static $logger = function($sql) { print_r($sql); }; But apparently PHP can't handle that. Ok, so I made a static init method: public static $logger; static function init() { /* if (!Base::logger) */ Base::logger = function($sql) { print_r($sql); }; } And call it at the end of the

Python: Nested Class Inheritance

What should I be aware before moving forward. I have a feeling sooner or later something would go wrong... with cPickle , pickle or may be it would be a PyQt drag-and-dropt?.. if so then why would the problem arise? class Base(dict): def

Issues with PHP classes and WordPress

问题 I am currently trying to add new options to the Rename wp-login.php because it is barely being updated. The owner also allowed me to add new options to it. The plugin functionality allows you to 'rename' /wp-admin/ and wp-login.php to a different location. I barely have any knowledge about PHP classes and, you guessed it, the whole plugin is basically created using PHP classes. What I am trying to do: When the field is empty, revert everything to /wp-admin/ . Basically a disable option; I've
