			0 ignored issues – show Coding Style Compatibility introduced 2018-02-25 17:05 UTC by Report Bug Copy Issue Report The function modx_sanitize_gpc() 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...
