Two simple php questions
Posted on 2006-11-01
i have two simple php questions. 1) I am uploading images and rename each image file to numbers by using time () function.. images name become like this 1162411085.jpg... my question is that what if 100 people are trying to upload files simultaneously... will this cause to upload error? i think php server is multi threaded so it can take many requests at once.
second question.. i am not quite professional in php.. just switched to php.. i want to track members and guests online on the website.. in asp there is an object Application where we store this kind of information in global.asa.. is there anything similiar in php too?
