Auto Generating Password with array()

[kumschick]

Hi,

I want to auto generate a password that is betreen 8 and 14 chr.
based on letter and numbers.

$pwdlgt = array("8";"9";"10";"11";"12";"13";"14")

$pwdenum = array("a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z","A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z","0","1","2","3","4","5","6","7","8","9");

I'm trying, and my array() is always taking number. and never bigger then 2 digits. why?

// f.ex.: 54

Thx

First thing's first, you can simplify your arrays with the [man]range()[/man] function. Secondly, post some code so we can see what you are doing to physically generate the password.
For Example:

$pwdlt = range(8, 14);
$numbers = range(0, 9);
$upperletters = range("A", "Z");
$lowerletters = range("a", "z");
$pwdenum = array_merge($lowerletters, $upperletters, $numbers);
print_r($result);

(A few more lines of code, but ensures you get everything)

Secondly, here is a script to generate a random password 8-14 characters long, using the array with all the lowercase, uppercase, and numbers in the array...

function randompw(){
	global $randpw;
	$pwdlt = range(8, 14);
	$numbers = range(0, 9);
	$upperletters = range("A", "Z");
	$lowerletters = range("a", "z");
	$pwdenum = array_merge($lowerletters, $upperletters, $numbers);

srand((float)microtime() * 1000000);
shuffle($pwdenum);
shuffle($pwdlt);
//print_r($pwdenum);
//echo "<br /><br />";
//print_r($pwdlt);

$randpw = "";
for($i = 0; $i < $pwdlt[0]; $i++){
	$randpw .= $pwdenum[$i];
}
return $randpw;
}

Usage:

randompw();
echo $randpw;

how do you do a lost password

do you use a similar code to that? that sends to their email

You could use something like that to generate a random password to send to someone, sure...
