I have an image uploading script in which i use the following setup to assign names to uploaded images;
$saltdate = date( 'U' );
$saltuser = $_SERVER[REMOTE_ADDR];
$saltname = md5($saltdate.$saltuser);
// Recieve, Process, Save uploaded image
// Update database with image name
The problem that i encounter is that after processing/saving the image, when its time to add this file name to the database, the value of $saltdate seems to have changed and i will get a file name in the database that doesnt exist.
How can i make sure that the value doesn't change once i establish it?
