		0 ignored issues – show Security Best Practice introduced 2017-04-19 20:34 UTC by Report Bug Copy Issue Report It seems like you do not handle an error condition here. This can introduce security issues, and is generally not recommended. If you suppress an error, we recommend checking for the error condition explicitly: // For example instead of @mkdir($dir); // Better use if (@mkdir($dir) === false) { throw new \RuntimeException('The directory '.$dir.' could not be created.'); } Loading history...

		0 ignored issues – show Coding Style Compatibility introduced 2017-07-31 16:04 UTC by Report Bug Copy Issue Report The method `do_exit()` contains an exit expression. An exit expression should only be used in rare cases. For example, if you write a short command line script. In most cases however, using an `exit` expression makes the code untestable and often causes incompatibilities with other libraries. Thus, unless you are absolutely sure it is required here, we recommend to refactor your code to avoid its usage. Loading history...
