PHP Debug console
Je kan deze class makkelijk gebruiken voor bv het kijken welke variablen er allemaal in je $_GET komen, in je $_POST etc. Je kan ook heel makkelijk opvragen welke php.ini settings je wilt bekijken. met debug extra kan je bijvoorbeeld kijken welke functies er geladen zijn en welke je zelf heb gemaakt (zelfde met interfaces, classes en extensies etc.) Met deze class kan je debuggen hieronder valt oa: php.ini settings (een paar standaard, maar je kan het aanpassen) globals bekijken (debug) geladen extensies bekijken (debug_extra) declared classes (debug_extra) declared interfaces (debug_extra) defined constants (debug_extra) defined functions (debug_extra) includes files (debug_extra) geladen extensies (debug_extra) functies: print_r met standaard $this->print_array($array, $echo_array = true) array stats printen, geef comment op eerste regel dus begin bij 1 (human readable) $this->array_stats($array) instellingen kan je aanpassen, zie script welke dat zijn.
