업로드에 문제가 있어서 호스팅 회사에 문의를 했더니

ini_set()  를 이용해서 php.ini 를 생성해야 한다는 얘기를 해 줬습니다. (확실하진 않지만)

무슨 소리인지 이해가 안되네요.. 어떻게 하면 좋으련지..

답변 :
Thank you for contacting Online Support. You will need to create and configure your own php.ini file since you do not have access to the default php.ini file within your hosting account. Most values can be overridden by using the ini_set() construct to change the value. We are unable to offer support for this, however, you may refer to the PHP Manual for further assistance. Please note that there are certain features that are disabled due to security reasons, therefore, not all modifications made to your php.ini file will be guaranteed to work on our shared hosting servers.
