[dvwhi]

hi i have a code and i need some help!! im making a password genorator and i have a while loop and it shows 4 codes eg. 11123-11123-11123-11123 but it makes this in the while and i want to make the output of the whil into a varible and then add it to my sql database here is code

function password(){

 // start with a blank password
  $password = "";

  // define possible characters
  $possible = "".$_SESSION['numeric']."".$_SESSION['alpha']."".$_SESSION['mixed'].""; 

  // set up a counter
  $i = 0; 

  // add random characters to $password until $length is reached
  while ($i < $_REQUEST['length']) { 

// pick a random character from the possible ones
$char = substr($possible, mt_rand(0, strlen($possible)-1), 1);

// we don't want this character if it's already in the password
if (!strstr($password, $char)) { 
  $password .= $char;
  $i++;
}

  }

  // done!
  echo"$password";
}
while ($p < $_REQUEST['times']) {
if($p < 3){$a="-";}else{$a="";}
$code1=password();
echo"$a";
$p++;}

You have two loops in that function. The second one produces output and the first one puts a string into a variable (then outputs the content of that variable). If you want the second one to put its output into a variable, put it into a variable in the same way that you do it in the first loop.
