Unique Name for File

[savagenoob]

Whats the easiest way to rename uploaded files to a unique name that would never be duplicated?

I don't think as that would be possible, unless you wrote in a clause to say if this exists, generate another, but personally functions like rand(0,999); and shuffle() could help generate a string:-

 

$arrayOfChars = str_split('0123456789QWERTYUIOPASDFGHJKLZXCVBNM');

 

shuffle($arrayOfChars);

 

echo $arrayOfChars[rand(0,36)].$arrayOfChars[rand(0,36)].$arrayOfChars[rand(0,36)];

 

something like that would produce a string with 'jumbled' content that would have countless permutations.. I must stress, this is just for example, it may not work like that; but I think it could ;-p

using the date/time as the name - would generaly produce and ordered filename system

Use a sequence with a very large amounts of permutations available, then check if file exists, if exists from another and loop it.
