+ * Apply html_entity_decode() to a string while re-entitising HTML
+ * special char entities to prevent them from being decoded back to their
+ * unsafe original forms.
+ *
+ * This relies on html_entity_decode() not translating entities when
+ * doing so leaves behind another entity, e.g. > if decoded would
+ * create > which is another entity itself. This seems to escape the
+ * usual behaviour where any two paired entities creating a HTML tag are
+ * usually decoded, i.e. a lone > is not decoded, but <foo> would
+ * be decoded to <foo> since it creates a full tag.
+ *
+ * Note: This function is poorly explained in the manual - which is really
+ * bad given its potential for misuse on user input already escaped elsewhere.
+ * Stackoverflow is littered with advice to use this function in the precise
+ * way that would lead to user input being capable of injecting arbitrary HTML.
