So, how do I generate a string like this:
Z8Yjv.jpg
I went to get a photo of a user here from Stack-OverFlow and the name of the photo came like this. I had thought of something like this:
<?php
$string = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
echo substr(str_shuffle($string), 0, 6);
?>
What is the probability of generating the same string? ... And if it is wrong that way, then what is the best way to generate it?
