Generating Unique ID

[eluser]Randy Casburn[/eluser]
Rather than write all this stuff yourself, you could rely on what is already written for you. While the php function produces a string 13 characters long by default, it works and you could pull from it what you need. Here it is without any fancy foot work:

Code:

$unique =uniqid();

A better randomization would be:

Code:

$moreUnique = md5(uniqid(rand(), true));

That's directly out of the PHP manual. No credit to me.

If you are using MySQL, you could actully SELECT UUID from MySQL to get a standard UUID as well without any coding other than the query.

No reason to reinvent all this stuff.
