Most of the posts here are about generating passwords, and thats fine, but I wanted to point out
something I saw as I glanced through a few of your functions... I'm using the function below as
an example but I saw 3 others that had the same problem...
the line in the for loop will generate an error because remember when your using a variable as an
array 0 is the first entry so strlen($A) - 1 must be used in this case
function GenPass($_maxlen) {
$A = "abcdefghijklmnopqrstuvwxyz0123456789";
for ($i=0;$i<=$_maxlen;$i++) {
$code .= $A[rand(0,strlen($A))];
// change this line to:
// $code .= $a[rand(0,strlen($A)-1)];
}
return $code;
}
