Random Character String

Is there a way of generating an 8 character random string in PHP?

Is there a way to ignore UPPER and lower case when you are using the SELECT
command to find a record in the mySQL table?

I know this isn't an HTML forum ... I have one more question which is more
HTML in nature. I don't want some of the web pages to be indexed that my
PHP scripts are creating. Is there a tag you know of to prevent this from
happening?

RE: Random Character String

i use this function to generate a random 7 letter password...simple change
to make it 8
function change_password($id, $password)
{
//generate a random password
$pass = "";
$salt = "abchefghjkmnpqrstuvwxyz0123456789";
srand((double)microtime()*1000000);
$i = 0;
while ($i <= 7) {
$num = rand() % 33;
$tmp = substr($salt, $num, 1);
$pass = $pass . $tmp;
$i++;
}
//change the password in the db
$sql = "update cust_info set cust_pw ='".md5($pass)."', temp_pass = 1 where
cust_lg = '$id' and cust_pw = '$password'";
$result = connect($sql);
if ($result){
return $pass;
}else{
change_password($id, $password);
}
}//end function


SQL is case insensitive for most queries. but you can use UPPER or LOWER to
force case to one or the other if you feel its a problem


for the html tag

Re: Random Character String

Hi,
Look at uniqueid function,
but it gives some lengthy string. You can use string functiions for
your specific purpose.
