echo $input[array_rand($all)];
This gets a random index in the array and then echos the value.

Yes, I tried it earlier. But it does not pull random name. " array_rand() expects parameter 1 to be array, boolean given in" – Mar 19 '18 at 16:16

So that would mean there is something wrong with how you've setup the $all variable. Can you post the var_dump or print_r of that variable after the explode is called? – dukedevil294 Mar 19 '18 at 16:19

Get random characters:
rand_chars("ABCEDFG", 10); // Output: GABGFFGCDA
Get random number:
echo rand(1, 10000); // Output: 5482
If you want to have a random string based on given input:
$chars = "1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
$clen = strlen( $chars )-1;
$id = '';
$length = 10;
for ($i = 0; $i < $length; $i++)
{
$id .= $chars[mt_rand(0,$clen)];
}
echo ($id); // Output: Gzt6syUS8M

` tags? Why are you assigning the result of a call to `print_r` and then echo-ing it? This looks like the code you end up with after trying lots of things and not removing them when they don't work. – iainn Mar 19 '18 at 16:07
