text: difference between move and copy command in php?   the copy command is used to copy one file to a specific location. i haven't come across a move command, but if there is one, then it probably moves a file to a specific location (i found that the rename command can be used to move a file from one directory to another)  after using the copy command, you get two copies of a file, in different locations. after moving a file, you still have one copy of that file.
