A friend of mine showed me this code recently.
function firstLogin_string() {
mt_srand(make_seed());
$pool = "AaBbCcDdEeFfGgHhIiJjKkLlM";
$length = 26;
for($i=0; $i < $length; $i++) {
$key .= $pool[mt_rand(0,strlen($pool)-1)];
}
return $key;
}
look at the for loop. $pool is not an array but is being treated as such and
the key happens to be the position in $pool and it'll take that letter and
save it to $key. I've never seen this done before. What is this method
called and what other neat tricks can you do in respect to this?
