		0 ignored issues – show Coding Style Compatibility introduced 2017-01-24 06:58 UTC by Report Bug Copy Issue Report For compatibility and reusability of your code, PSR1 recommends that a file should introduce either new symbols (like classes, functions, etc.) or have side-effects (like outputting something, or including other files), but not both at the same time. The first symbol is defined on line 31 and the first side effect is on line 23. The PSR-1: Basic Coding Standard recommends that a file should either introduce new symbols, that is classes, functions, constants or similar, or have side effects. Side effects are anything that executes logic, like for example printing output, changing ini settings or writing to a file. The idea behind this recommendation is that merely auto-loading a class should not change the state of an application. It also promotes a cleaner style of programming and makes your code less prone to errors, because the logic is not spread out all over the place. To learn more about the PSR-1, please see the PHP-FIG site on the PSR-1. Loading history...

Did you forget a USE statement, or did you not list all dependencies? This error could be the result of: 1. Missing dependencies PHP Analyzer uses your `composer.json` file (if available) to determine the dependencies of your project and to determine all the available classes and functions. It expects the `composer.json` to be in the root folder of your repository. Are you sure this class is defined by one of your dependencies, or did you maybe not list a dependency in either the `require` or `require-dev` section? 2. Missing use statement PHP does not complain about undefined classes in `ìnstanceof` checks. For example, the following PHP code will work perfectly fine: if ($x instanceof DoesNotExist) { // Do something. } If you have not tested against this specific condition, such errors might go unnoticed.

Did you maybe forget this after debugging? Sometimes obsolete code just ends up commented out instead of removed. In this case it is better to remove the code once you have checked you do not need it. The code might also have been commented out for debugging purposes.
