Description
Hi! i Just made this controller to analyze wheter a system class has dynamically declared properties. Ithink this may help to adapt CI3 to the neew PHP 8.3 without using [#AllowDynamicProperties] argument that can be depecated in future versions.
Cannot detect if a property is inherited! so in some cases, there can be false positives.
