php array_key_exists, !empty and isset fails for no reason?
问题 php 7.0.8 on ubuntu 16.0.4 LTS could somebody give me a hint why an array key check would fail when the key clearly exists, program execution just stops, with no explanation even with all error reporting enabled. The data type held in the array element is a string containing a torrent file downloaded from fedora website https://torrents.fedoraproject.org/ other functions fail here aswell such as !empty on the array key the key in this instance is 0 if(array_key_exists($index, $this->_webpage)
